    Transphorm Introduced SuperGaN® TOLT FET

    3 Min Read

    Transphorm, Inc. introduced the SuperGaN® TOLT FET. With an on-resistance of 72 milliohms, the TP65H070G4RS transistor is the industry’s first top-side cooled surface mount GaN device in the JEDEC-standard (MO-332) TOLT package. The TOLT package offers flexibility of thermal management to customers where system requirements do not allow for the more conventional surface mount devices with bottom-side cooling.

    The thermal performance of the TOLT is similar to that of the widely used, thermally robust TO-247 through-hole packages and delivers the added benefit of highly efficient manufacturing processes enabled by SMD-based printed circuit board assembly (PCBA).

    The TP65H070G4RS leverages Transphorm’s robust, high performance 650-volt normally-off d-mode GaN platform offering improved efficiency over silicon, silicon carbide, and other GaN offerings via lower gate charge, output capacitance, crossover loss, reverse recovery charge, and dynamic resistance.

    The SuperGaN platform advantages combined with the TOLT’s better thermals and system assembly flexibility results in a high performance, high reliability GaN solution for customers seeking to bring to market power systems with higher power density and efficiency at an overall lower power system cost.

    Transphorm is engaged with multiple global partners for high power GaN, including lead customers in server and storage power, a global leader in the energy/microinverter space, an innovative manufacturer of off-grid power solutions, and a leader in satellite communications.

    “Surface mount devices such as the TOLL and the TOLT offer various benefits such as lower internal inductance as well as simpler board mounting during manufacturing. The TOLT adds to that more flexible overall thermal management with through-hole like thermal performance by using top-side cooling,” said Philip Zuk, SVP Business Development and Marketing, Transphorm.

    “These devices are commonly found in mid to high power system applications for key market segments including high performance computing (Server, Telecom, AI Power), Renewables and Industrial, and Electric Vehicles, some of which our GaN technology already powers today. we’re very excited to enable our customers to realize additional system level benefits with TOLT SuperGaN solutions.”

    Today’s product release comes on the heels of Transphorm’s recent introduction of its three new TOLL FETs. Addition of the TOLT expands the company’s product offerings yet again. Its availability highlights Transphorm’s commitment to supporting customer preferences by making its SuperGaN platform accessible in various packages across the widest power range.

    Toshiba Released Two 600V IPDs

    2 Min Read

    Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched two products of 600V small intelligent power device (IPD) for brushless DC motor drive applications such as air conditioners, air cleaners, and pumps. Volume shipments of “TPD4163K” and “TPD4164K,” which have output current (DC) ratings of 1A and 2A, respectively, start today.

    Both new products are housed in a through hole type HDIP30 package, which reduces the mounting area by approximately 21% against Toshiba’s previous products. This helps reduce the size of motor drive circuit boards.

    As power supply voltage may fluctuate significantly in regions with unstable power supply, the voltage has been increased from the 500V of Toshiba’s previous products[1] to 600V, which improves reliability.

    A “Reference Design for Sensorless Brushless DC Motor Drive Circuit” that utilizes the functions of the new TPD4164K with a TMPM374FWUG microcontroller with vector control engine is available from today on Toshiba’s website.

    Toshiba will continue to expand its product line-up with improved characteristics, to improve design flexibility, and to contribute to carbon neutrality through energy-saving motor control.

  • Siltronic Confirms Q3 2023 was Weaker in Demand from Semiconductor Industry

    Siltronic Confirms Q3 2023 was Weaker in Demand from Semiconductor Industry

    7 Min Read

    As expected, the business performance of Siltronic AG in Q3 2023 was marked by weaker demand from the semiconductor industry. Quarterly sales were EUR 349.1 million, 13.5 percent lower than the previous quarter (Q2 2023: EUR 403.7 million).

    Despite a noticeable decline in wafer volumes, sales prices continued to be stable. Thanks to this development, the EBITDA margin in the reporting quarter remained at a solid level of 28.4 percent and even reached 29.6 percent after nine months. As the Executive Board expects a slight improvement in Q4 compared to Q3, the annual outlook is confirmed and specified within the communicated range: Group sales for the financial year 2023 are expected to be between 15 and 17 percent below the previous year’s value (exchange rate EUR/USD 1.10), and the EBITDA margin is expected to reach a value between 28 and 30 percent.

    Driven by the megatrends artificial intelligence, digitalization, and electromobility, Siltronic is preparing for the next growth phase. The company is well-prepared for this with the expansion of global production capacities in Singapore and investments to improve the product mix in Freiberg.

    “Despite the expected decline in wafer demand, Siltronic achieved a solid EBITDA margin of 28.4 percent in Q3. Thanks to the continued stable sales prices for our wafers, we are confident in achieving a respectable EBITDA margin between 28 and 30 percent for the full year. To further support the expected growth in the semiconductor industry in the coming years, we are investing in our new fab in Singapore and are close to producing the first wafers,” commented Dr. Michael Heckmeier, CEO of Siltronic AG, on the development.

    Business Development in Q3 2023

    Siltronic generated sales of EUR 349.1 million in Q3 2023, down by 13.5 percent compared to the previous quarter (Q2 2023: EUR 403.7 million). After nine months, the company reported sales of EUR 1,157.2 million, down 13.2 percent year-on-year (Q1-Q3 2022: EUR 1,333.2 million). This development was due to the lower wafer area sold. Sales prices remained stable compared to the previous periods and FX changes also had no
    significant impact.

    Cost of sales decreased by 9.7 percent in Q3 2023 compared to the previous quarter and decreased by 2.7 percent in the first nine months of 2023 compared to the period January to September 2022. The decline in sales was more pronounced than the reduction in cost of sales, both quarter-on-quarter and year-on-year. In the quarterly comparison, this is mainly due to increased depreciation.

    In a year-on-year comparison, the most important reasons for the disproportionately low reduction in cost of sales are a reduced dilution of fixed costs, higher depreciation and cost increases in labor costs, raw materials and supplies. As a result, the gross profit fell by EUR 25.4 million compared to the previous quarter and by EUR 151.9 million compared to the previous year. The gross margin fell from 33.4 percent to 25.3 percent year-on-year. Q3 includes positive currency effects of EUR 9.9 million (Q2 2023: EUR 6.3 million), which are shown in the balance of other operating income and expenses.

    EBITDA in Q3 was EUR 99.1 million and thus EUR 19.5 million below the previous quarter (Q2 2023: EUR 118.6 million). The EBITDA margin remained at a good level of 28.4 percent (Q2 2023: 29.4 percent). After nine months, Siltronic reported EBITDA of EUR 342.8 million (Q1-Q3 2022: EUR 503.5 million – comparable: EUR 453.5 million) and an EBITDA margin of 29.6 percent (Q1-Q3 2022: 37.8 percent – comparable: 34.0 percent). It should be noted that a one-off termination fee of EUR 50.0 million was received in Q1 2022 as a result of the failed tender offer by GlobalWafers.

    Due to the lower EBITDA and higher depreciation and amortisation, EBIT amounted to EUR 46.4 million in Q3 (Q2 2023: EUR 70.3 million) and to EUR 194.5 million after the first nine months (Q1-Q3 2022: EUR 370.8 million). Net profit for the quarter was EUR 35.1 million (Q2 2023: EUR 61.4 million) and earnings per share were EUR 1.10 (Q2 2023: EUR 1.83). Net income for the period from January to September was EUR 169.0 million (Q1-Q3 2022: EUR 315.8 million) and earnings per share of EUR 5.13 after EUR 9.46 in the same period of the previous year.

    Continued good balance sheet quality as a basis for financing investments

    With an equity ratio of 49.3 percent as of September 30, 2023 (December 31, 2022: 51.0 percent), Siltronic continues to have a good balance sheet quality. In the first nine months of the financial year, EUR 51 million more customer prepayments were received than refunded. In addition, the last tranche of a loan to finance our investments was drawn in Q3, as planned.

    “Our balance sheet reflects a favourable equilibrium, as about half of our capital is equity. The financing of our new fab in Singapore is based on a broad foundation. This consists of high customer prepayments, which were negotiated within the framework of the long-term agreements concluded. In addition, the financing is based on Siltronic’s sustainable and solid cash flows and the concluded debt financing,” adds Claudia Schmitt, CFO of Siltronic AG.

    Cash and cash equivalents and financial investments fell by EUR 542.8 million to EUR 508.1 million in the first nine months of 2023. This was due to payments for capital expenditure including intangible assets of EUR 904.6 million for the construction of the new 300 mm fab in Singapore and the distribution of the dividend to the shareholders of Siltronic AG of EUR 90.0 million.

    The cash outflows were offset by cash inflows in the same period of EUR 324.3 million from the cash flow from operating activities. Due to the high investments, the net cash flow, which does not take into account the inflows and outflows from prepayments, was negative at EUR -631.3 million, as expected. This primarily led to Siltronic reporting net financial debt of EUR -315.7 million at the end of September 2023.

    Outlook 2023 confirmed and specified: Group sales expected to be 15 to 17 percent below the previous year and EBITDA margin between 28 and 30 percent

    In view of the Q3 2023 development, which is in line with expectations, the Executive Board has confirmed the full-year guidance communicated in H1 2023 and confirmed it at the upper end of the range. Even though the end of the weaker demand due to inventory corrections by chip manufacturers and their customers is not expected in Q4 2023, sales in Q4 2023 are expected to be higher than in Q3.

    Therefore, Siltronic continues to expect wafer volumes to decline by around 15 percent year-on-year in 2023. Sales prices are expected to remain stable. Accordingly, the full-year guidance has been concretised and group sales are now expected to be 15 to 17 percent (exchange rate EUR/USD: 1.10) below the previous year’s record level of EUR 1,805.0 million. We expect that the increased inventories will also have an impact into the year 2024.

    The EBITDA margin in 2023 is also forecast to be significantly lower at 28 to 30 percent, but at the upper end of the range guided in July. In addition to the reduced sales volume, which at the same time leads to a lower dilution of fixed costs, higher costs of less than EUR 40 million due to inflation as well as the aforementioned one-time effect from the previous year contribute to the decline. The stronger euro year-on-year is weighing on the operating result, but Siltronic can expect a positive result from currency hedges in 2023, after a negative contribution in the previous year. The tax rate is expected to be around 15 percent in 2023.

    As already communicated in H1 2023, capital expenditure including intangible assets is expected to be at a level of approximately EUR 1.3 billion (2022: EUR 1,074 million). In 2024, Capital expenditure including intangible assets is expected to decrease significantly by more than half. Depreciation is expected to be around EUR 200 million in the financial year.

    Megatrends such as artificial intelligence, digitalisation and electromobility form the basis for the expected medium- to long-term growth spurt

    Due to the rapidly increasing number of end applications based on megatrends such as artificial intelligence, digitalisation and electromobility, which will lead to a noticeable increase in wafer demand, Siltronic sees great growth potential in the medium and long term. The company is systematically preparing for this by investing heavily in its global production network. The main focus of expenditure is on building up new production capacities in Singapore (FabNext). Siltronic has also invested heavily in improving its product mix. For example, the extension of the crystal pulling hall in Freiberg was successfully inaugurated in September.

    3 Min Read

    DENSO CORPORATION hosted a press conference at JAPAN MOBILITY SHOW 2023 held at Tokyo Big Sight on October 26. Shinnosuke Hayashi, President and COO introduced the strategy to maximize company’s contributions to “Green” and “Peace of Mind.”

    Shinnnouke Hayashi, President and COO of DENSO CORPORATION said that it is a great pleasure that the Tokyo Motor Show, which has attracted much public attention for decades, has been renamed the JAPAN MOBILITY SHOW. This change reflects the fact that we are entering an era of creating new value by addressing various issues from the viewpoint of a mobility-centered society instead of just vehicles and by connecting people and technologies across industries. This means that DENSO must meet major challenges.

    To evolve from “a Tier 1 supplier that supports the auto industry “to “a Tier 1 supplier that supports a mobility-centered society” to create value for more diverse customers, the company addresses three intiatives. To promote these three initiatives, DENSO will recruit new employees in the electrification and software field and actively shift the employees from the mature field to the electrification and software fields and strengthen about 4,000 employees during the four years from 2022 to 2025.

    • The contribution to the “evolution of mobility”
      In the “Green” field, “the environment”, in addition to the product lineup in the “horizontal” direction to enable installation in HEVs, PHEVs, BEVs, and FCEVs, the lineup will be expanded in the “vertical” direction ranging from large systems, which link electrification products with energy management, to components, including power modules, thereby meeting the needs of various customers as BEVs proliferate and helping to achieve carbon neutrality in respective countries. In the “Peace of Mind” field, “worry-free society”, in addition to around-vehicle monitoring systems, DENSO will focus on driver status monitoring systems and cloud-based large systems, which connect with the social infrastructure. Through these efforts, the company will help eliminate fatalities.

      Furthermore, DENSO will extend its commitment to the evolution of mobility to the sky to help realize more freedom of traveling and expand the possibilities of mobility.

    • The challenge to “to create new value”
      DENSO has been studying the possibility of developing and commercializing many technologies in non-mobility fields, including energy, food and agriculture, and the circular economy. Specifically, the company plans to market energy system products such as Solid Oxide Electrolysis Cell and Solid Oxide Fuel Cell in 2024 and beyond.

    • Strengthening semiconductors and software
      In terms of semiconductors, DENSO will actively invest about 500 billion yen by 2030. DENSO will triple the scale of the business from the current level by 2035. To expand production, the company must ensure stable procurement of materials. Thus, DENSO will forge strategic partnerships with various companies.

      In the softaware field, the implementation phase to embody concepts, the company will accelerate the planning of electronic platform and over-the-air technology development based on user needs while strengthening partnerships with various customers and promote integrated development across companies. DENSO will increase the number of software engineers and improve their skills and integrate two group companies which have excellent proprietary technologies, into DENSO. One is NSITEXE, which specializes in the semiconductor intellectual property, and the other is AUBASS, which specializes in developing basic in-vehicle software. DENSO will double the speed of development by applying specialized AI, which incorporates company’s knowledge and experience gained through in-vehicle software.
