    Many industrial applications today are transitioning to higher power levels with minimized power losses, which can be achieved through increased DC link voltage. Infineon Technologies AG addresses this challenge by introducing the CoolSiC™ Schottky diode 2000 V G5, the first discrete silicon carbide diode on the market with a breakdown voltage of 2000 V. The product family is suitable for applications with DC link voltages up to 1500 VDC and offers current ratings from 10 to 80 A. This makes it ideal for higher DC link voltage applications such as in solar and EV charging applications.

    The product family comes in a TO-247PLUS-4-HCC package, with 14 mm creepage and 5.4 mm clearance distance. This, together with a current rating of up to 80 A, enables a significantly higher power density. It allows developers to achieve higher power levels in their applications with only half the component count of 1200 V solutions. This simplifies the overall design and enables a smooth transition from multi-level topologies to 2-level topologies.

    In addition, the CoolSiC Schottky diode 2000V G5 utilizes the .XT interconnection technology that leads to significantly lower thermal resistance and impedance, enabling better heat management.   Furthermore, the robustness against humidity has been demonstrated in HV-H3TRB reliability tests. The diodes exhibit neither reverse recovery current nor forward recovery and feature a low forward voltage, ensuring enhanced system performance.

    The 2000 V diode family is a perfect match for the CoolSiC MOSFETs 2000 V in the TO-247Plus-4 HCC package that Infineon introduced in spring 2024. The CoolSiC diodes 2000 V portfolio will be extended by offering them in the TO-247-2 package, which will be available in December 2024. A matching gate driver portfolio is also available for the CoolSiC MOSFETs 2000 V.

    3 Min Read

    Affordability combined with high performance and efficiency is the key to making electric mobility accessible to a broader market. That’s why Infineon Technologies AG is introducing the HybridPACK™ Drive G2 Fusion, establishing a new power module standard for traction inverters in the e-mobility sector.

    The HybridPACK Drive G2 Fusion is the first plug’n’play power module that implements a combination of Infineon’s silicon and silicon carbide (SiC) technologies. This cutting-edge solution provides an ideal balance between performance and cost efficiency, giving more choice in the optimization of inverters.

    One of the main differences between silicon and SiC in power modules is that SiC has a higher thermal conductivity, breakdown voltage and switching speed, making it more efficient, but also more expensive than silicon-based power modules. With the new module, the SiC content per vehicle can be reduced, while maintaining vehicle performance and efficiency at a lower system cost. For example, system suppliers can realize nearly the system efficiency of a full SiC solution with only 30 percent SiC and 70 percent silicon area.

    “Our new HybridPACK Drive G2 Fusion module underlines Infineon’s innovation leadership in the automotive semiconductor industry,” said Negar Soufi-Amlashi, Senior Vice President & General Manager High Voltage at Infineon’s Automotive division. “Addressing the demand for greater e-mobility range, this technological breakthrough smartly combines silicon carbide and silicon.

    HybridPACK Drive G2 Fusion expands Infineon’s HybridPACK Drive power module portfolio and can be quickly and easily integrated in vehicle components or modules without requiring complex adjustments or configurations. The HybridPACK Drive G2 Fusion module features up to 220 kW in the 750 V class. It ensures high reliability over the entire temperature range from -40 °C to +175 °C and improved thermal conductivity.

    The unique properties of Infineon’s CoolSiC™ technology and its silicon IGBT EDT3 technology with very fast turn-on enable the use of a single gate driver or dual gate drivers. This allows easy re-design from full silicon or full SiC based inverters to a fusion inverter. Generally, Infineon’s holistic expertise in SiC MOSFET and silicon IGBT technology, power module packaging, gate drivers as well as sensors enables premium products with cost savings at system level. One example is the integration of Swoboda or XENSIV™ Hall sensors in the HybridPACK Drive package for more precise and efficient motor control.

    Infineon will showcase the new HybridPACK Drive G2 Fusion at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).

    “This $750 million federal investment is a testament to Wolfspeed’s unique leadership in silicon carbide semiconductor manufacturing, and I applaud Wolfspeed’s continued commitment to North Carolina,” said Senator Thom Tillis. “I was proud to vote for the CHIPS and Science Act to provide the funding for this investment in North Carolina and to support our economic and national security.”

    “North Carolina continues to be a leader in cutting-edge manufacturing that is vital to our country’s national and economic security,” said Senator Ted Budd. “This new Wolfspeed site in Siler City will bring good-paying jobs to the area and is an important first step in making sure America has secure supply chains for critical semi-conductors.”

    “We are pleased to expand our investment in Wolfspeed by providing additional capital in support of the company’s build out of its leading silicon carbide capabilities,” said Apollo Partner Joseph Jackson. “We believe Wolfspeed is at the forefront of a critical transformation in sustainable transportation and ensuring that the company has durable capital access to complete its expansion plans will help solidify its leadership in this space. Along with our lending consortium, which includes multiple funds that also own substantial equity stakes in the company, we believe this strategic investment will drive significant long-term value while advancing key tenets of the CHIPS and Science Act.”

    These proposed funds, which are expected to be received upon milestone achievements in the coming years, would enable Wolfspeed to complete its multi-billion-dollar greenfield U.S. capacity expansion plan, which consists of the largest and most advanced 200mm silicon carbide footprint in the world. In addition to the proposed direct funding, Wolfspeed intends to benefit from the U.S. Treasury Department Investment Tax Credit of up to 25% of the qualified capital expenditures primarily related to its construction and installation of equipment at The John Palmour Manufacturing Center for Silicon Carbide in Siler City, NC and completion of the Mohawk Valley Fab M-Line West Expansion in Utica, NY.
