Automotive CoolSiC™ MOSFET 1200 V in Q-DPAK

Our new Automotive CoolSiC™ MOSFET 1200 V in Q-DPAK is tailored to address OBC/DC-DC applications for 800V Automotive architecture: leveraging Top-Side-Cooling (TSC) technology, it can provide customers with an outstanding thermal performance, easier assembly and reduced system cost. Compared to back-side cooling, TSC provides an optimized PCB assembly, thus eliminating parasitic effects and providing much lower stray inductances.

Key features
  • 0 V turn-off
  • Creepage  4.8 mm
  • Symmetrical lead layout
  • .XT technology
Key benefits
  • Lower package parasitics
  • Lower switching losses
  • Simplified design
  • Optimized PCB assembly

Based on  SiC Gen1p technology, thanks to a 0V turn-off, it enables unipolar gate driving thus simplifying the design with less components on the PCB. With a creepage of 4.8mm, the package can achieve a working voltage exceeding 900V, with no additional coating for isolation. Customers benefit from lower package parasitics, experience lower switching losses and ease of design thanks to a symmetrical lead layout for higher thermal-cycling performance. Diffusion soldering of the chip through “.XT Technology” further improves the thermal dissipation.
