Infineon presents new 600V CoolMOS 8 SJ MOSFET family

12th June 2024

Infineon Technologies introduces the 600V CoolMOS 8 high voltage superjunction (SJ) MOSFET product family.

The devices combine the best features of the 600V CoolMOS 7 MOSFET series and are the successors to the P7, PFD7, C7, CFD7, G7, and S7 product families. The new superjunction MOSFETs enable cost-effective Si-based solutions that enhance Infineon's wide-bandgap offering. They are equipped with an integrated fast body diode, making them suitable for a wide range of applications such as server and industrial switched-mode power supply units (SMPS), EV chargers, and micro-solar. 

The components come in SMD QDPAK, TOLL, and ThinTOLL 8 x 8 packages, which simplifies designs and reduces assembly costs. At 10V, the 600V CoolMOS 8 SJ MOSFETs offer 18% lower gate charge (Q g) than the CFD7 and 33% lower than the P7. At 400V, the product family offers a 50% lower output capacitance C OSS than the CFD7 and the P7. In addition, the turn-off losses (E oss) have been reduced by 12% compared to the CFD7 and the P7 and the reverse recovery charge (Q rr) is 3% lower compared to the CFD7. Furthermore, the devices offer the lowest reverse recovery time (t rr) on the market and the thermal performance has been improved by 14 to 42% compared to the previous generation.

With these features, the devices offer high efficiency and reliability in soft-switching topologies such as LLC and ZVS phase-shift full-bridge. They also provide excellent performance levels in PFC, TTF, and other hard-switching topologies. Due to their optimised R DS(on), the devices offer higher power density, allowing products in a Si-based super junction (SJ) technology to be reduced to a single-digit value of 7mΩ.

Infineon will showcase the 600V CoolMOS 8 SJ MOSFETs at the Infineon booth (Hall 7 / Booth 470) at PCIM 2024 in Nuremberg.


Samples of the 600 V CoolMOS 8 SJ MOSFETs are now available.

Infineon at the PCIM Europe 2024

PCIM Europe will take place in Nuremberg, Germany, from 11–13 June 2024. Infineon will present its products and solutions for decarbonisation and digitalization in hall 7, booths #470 and #169. Company representatives will also be giving several presentations at the accompanying PCIM Conference and Forums, followed by discussions with the speakers.
