Designed to meet the robust packaging requirements for the most demanding applications that require increased performance and reliability, the new GTPAK™ and GLPAK™ packages will first be available on AOS’ AOGT66909 and AOGL66901 MOSFETs respectively. Combining AOS-proven robust MOSFET technology with advanced packaging know-how, these devices provide low ohmic and high current capabilities, critical to reducing the number of parallel MOSFETs needed in high current designs such as in next-generation e-mobility and industrial applications.
The GTPAK offered with the AOGT66909 is a topside cooling package designed with a large exposed pad for more efficient heat transfer. The topside cooling technology transfers most heat to the heat sink mounted on the top exposed pad. This feature allows the GTPAK to offer a more effective thermal dissipation route than going through the PCB board, allowing a lower-cost PCB, such as FR4, to be used.
The GLPAK offered with the AOGL66901 is a gull-wing version of AOS’ successful TOLL package. It is designed using AOS’ advanced clip technology to achieve a high inrush current rating. The GLPAK with clip technology offers very low package resistance and parasitic inductance, improving EMI performance compared to other package types that employ standard wire bonding.
The GTPAK and GLPAK packages feature gull-wing leads, enabling excellent solder joint reliability even for insulated metal substrates (IMS) applications. This gull-wing construction also provides enhanced thermal cycling for IMS boards and other critical applications that must meet higher reliability objectives. AOS MOSFETs in the new GTPAK and GLPAK packages are manufactured in IATF16949-certified facilities and are compatible with automated optical inspection (AOI) manufacturing requirements.
“We are committed to delivering new solutions to help our customers meet or exceed their power performance requirements.

Toshiba Electronics Europe GmbH has launched an N-channel power MOSFET to address the growing market demand for improved efficiency in power supply circuits. The new TK024N60Z1 uses the proven DTMOSVI 600V series process with a super junction structure to achieve low on-resistance and reduced conduction losses. Applications include servers in data centres, switched-mode power supplies for industrial equipment, and power conditioners for photovoltaic generators.
The TK024N60Z1 has a drain-source on-resistance RDS(ON) of 0.024Ω (max), which is the lowest in the DTMOSVI 600V series. It also improves power supply efficiency, which reduces heat generation. Combined with the TO-247 package, which delivers high heat dissipation, the TK024N60Z1 offers good heat management characteristics.
Like other MOSFETS in the DTMOSVI 600V series, the TK024N60Z1 benefits from an optimised gate design and process. This reduces the value of drain-source on-resistance per unit area by approximately 13%. More importantly, drain-source on-resistance × gate-drain charge is reduced by approximately 52% compared to Toshiba’s conventional generation DTMOSIV-H series products with the same drain-source voltage rating. This means the DTMOSVI series, including the TK024N60Z1, offers a better trade-off between conduction loss and switching loss, which helps improve the efficiency of switched-mode power supplies.
To further improve power supply efficiency, Toshiba offers tools that support circuit design for switched-mode power supplies. These include the G0 SPICE model, which quickly verifies circuit function, and the highly accurate G2 SPICE models that reproduce transient characteristics.
The TK024N60Z1 N-channel power MOSFET exemplifies Toshiba’s commitment to continue expanding the DTMOSVI series and support energy conservation by reducing power loss in switched-mode power supplies.

SUMCO Corporation announced plans to transfer wafer production from the Miyazaki Plant of consolidated subsidiary SUMCO TECHXIV Corporation to other manufacturing facilities, with the aim of improving profitability by reorganizing the production of silicon wafers of 200 mm and smaller.
The current silicon wafer market environment is in a prolonged sluggish demand phase, due to such factors as the drop-off from extraordinary demand during the COVID-19 pandemic, and structural changes in the semiconductor supply chain occasioned by US-China friction.
Drawdown of 300 mm wafer inventories by customers is taking time, as semiconductor production adjustments continue; but overall demand is expected to recover gradually thanks to strong needs for leadingedge products for AI semiconductors and high-performance memory. Demand remains sluggish, however, for small-diameter wafers mainly for consumer, industrial, and automotive uses. Wafers of 150 mm and smaller, in particular, are expected to see falling demand, with customers shifting to 200 mm wafers or lowering their production capacity as manufacturing equipment reaches its end of life.
In this market environment, the SUMCO Group has decided to reorganize the Miyazaki Plant to improve efficiency through consolidation of the production capacity of small wafers. The Miyazaki Plant will become a factory solely for monocrystalline production, while wafer production will be transferred to other domestic plants in the SUMCO Group and to Indonesia, ending wafer production in Miyazaki by the end of 2026.
SUMCO intends to reassign employees affected by the reorganization to 300 mm wafer operations after the end of wafer production in Miyazaki. With this reorganization, expenses for business structural reforms have been posted for fiscal 2024 as extraordinary losses totaling 5.8 billion yen, consisting of an impairment loss on non-current assets of 4.6 billion yen and an inventory write-down, etc., of 1.2 billion yen.
The SUMCO Group is committed to ongoing efficiency-raising initiatives, including reorganization of production facilities. Moreover, with the accelerating pace of innovation in semiconductor technology, in addition to strategically making use of advanced manufacturing equipment currently under preparation for operation, we will focus management resources on modernizing equipment in existing 300 mm plants and boost our capacity for supplying leading-edge products for AI with their remarkable growth, as we strive to further raise our corporate value.

Mitsubishi Electric Corporation announced that it will begin shipping samples of two new S1-Series High Voltage Insulated Gate Bipolar Transistor (HVIGBT) modules, both rated at 1.7kV, for large industrial equipment such as railcars and DC power transmitters from December 26. Thanks to proprietary Insulated Gate Bipolar Transistor (IGBT) devices and insulation structures, the new modules offer excellent reliability and low power loss and thermal resistance, which are expected to increase the reliability and efficiency of inverters in large industrial equipment.
Mitsubishi Electric’s 1.7kV HVIGBT modules, first released in 1997 and highly regarded for their excellent performance and high reliability, have been widely adopted for inverters in power systems.
The new S1-Series modules incorporate Mitsubishi Electric’s proprietary Relaxed Field of Cathode (RFC) diode, which increases the Reverse Recovery Safe Operating Area (RRSOA) by 2.2 times compared to previous models for improved inverter reliability. In addition, the use of an IGBT element with a Carrier Stored Trench Gate Bipolar Transistor (CSTBT) structure helps reduce both power loss and thermal resistance for more efficient inverters.Furthermore, Mitsubishi Electric’s proprietary insulation structure increases the insulation voltage resistance to 6.0kVrms, 1.5 times that of previous products, resulting in more flexible insulation designs for compatibility with a wide range of inverter types.

Nexperia announced the launch of 16 new 80 V and 100 V power MOSFETs in the innovative copper-clip CCPAK1212 package, delivering industry-leading power density and outright performance. The innovative copper-clip design provides high current conduction, reduced parasitic inductance, and excellent thermal performance. These features make the devices ideal for motor control, power supplies, renewable energy systems, and other power-hungry applications.
The range also includes application-specific MOSFETs (ASFETs) designed for AI server hot-swap functions. With top-side and bottom-side cooling options, these MOSFETs in CCPAK provide high power density and reliable solutions. All devices are supported by JEDEC registration and Nexperia’s interactive datasheets for seamless integration.
The benchmark PSMN1R0-100ASF is a 0.99 mΩ 100 V power MOSFET capable of conducting 460 A and dissipating 1.55 KW of power, yet in a CCPAK1212 package footprint that occupies only 12mm x 12mm of board space. The PSMN1R0-100CSF offers similar statistics in a top-side cooled version.
The secret to this impressive performance is the internal construction of the devices. The “CC” in CCPAK1212 stands for copper clip, meaning that the power MOSFET silicon die is sandwiched between two pieces of copper, the drain tab on one side and the source clip on the other. With wire bonds entirely eliminated, such an optimized assembly offers a low on-resistance, reduced parasitic inductances, high maximum current ratings and excellent thermal performance.
CCPAK1212 NextPower 80/100 V MOSFETs are recommended for power-hungry industrial applications where high efficiency and high reliability are critical, including brushless DC (BLDC) motor control, switched-mode power supplies (SMPS), battery management systems (BMS) and renewable energy storage. The availability of such power-capable MOSFETs in a single package reduces the need for parallelism, simplifying designs and offering more compact, cost-effective solutions.
The Nexperia CCPAK1212 announcement also includes some new application specific MOSFETs (ASFETs) targeting the hot-swap function in increasingly powerful AI servers. These devices feature an enhanced safe operating area (SOA), providing superior thermal stability during linear mode transitions.
Across all these applications, the availability of top-side and bottom-side cooling options provides engineers a choice of thermal extraction techniques, especially helpful where dissipating heat through the PCB is impractical due to the sensitivity of other components.
“Despite offering market-leading performance, we know that some customers will be reticent to design-in a relatively new package”, stated Chris Boyce, Product Group General Manager at Nexperia. “For this reason, we have registered the CCPAK1212 with the JEDEC standards organization (reference MO-359). We followed a similar approach when we introduced the first LFPAK MOSFET package some years ago and as a result there are now many compatible devices available in the market. You are never on your own for long when your innovations offer genuine value to your customers”, concluded Boyce.
All the new CCPAK1212 MOSFET devices are supported with a range of advanced design-in tools, including thermally compensated simulation models. Traditional PDF datasheets are supplemented with Nexperia’s user-friendly interactive datasheets, which now incorporate a new “graph-to-csv” feature that allows engineers to download, analyze and interpret the data behind each device’s key characteristics. This not only streamlines the design process but enhances confidence in design choices.
Nexperia plans to extend CCPAK1212 packaging to power MOSFETs across all voltage ranges and also to its automotive qualified AEC-Q101 portfolios, addressing the evolving demands of next-generation systems with the highest current and thermal performance requirements.

Compared to previous-generation devices in the PowerPAK SO-8, the Vishay Siliconix SiRS5700DP slashes overall on-resistance by 68.3% and on-resistance times gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — by 15.4% while providing 62.5% lower RthJC and 179 % higher continuous drain current.
With the industry’s lowest on-resistance of 5.6 mΩ at 10 V and on-resistance times gate charge FOM of 336 mΩ*nC, the device released today minimizes power losses from conduction. This allows designers to boost efficiency to meet next-generation power supply requirements, such as 6 kW AI server power systems. In addition, the extremely low 0.45 °C/W RthJC of the PowerPAK SO-8S package enables continuous drain current up to 144 A to increase power density while providing robust SOA capability.
The SiRS5700DP is ideal for synchronous rectification, DC/DC converters, hot swap switching, and OR-ing functionality. Typical applications will include servers, edge computing, super computers, and data storage; telecom power supplies; solar inverters; motor drives and power tools; and battery management systems. RoHS-compliant and halogen-free, the MOSFET is 100 % Rg and UIS tested and complies with IPC-9701 criteria for more reliable temperature cycling. The device’s standard 6 mm by 5 mm footprint is fully compatible with the PowerPAK SO-8 package.
