ROHM - Super Junction MOSFET for Efficient Power Conversion

PrestoMOS™: Super Junction MOSFET with built-in FRD from ROHM Semiconductor

Rohm Superjunction MOSFETs chip images

ROHM's PrestoMOS™ series is ideal for power supplies with integrated inverter. Advanced fast recovery diode is implemented in body diode of the MOSFET, which reduces switching loss and improve efficiency in system level. Standard packages: TO-220FM, TO-247, DPAK and D2PAK are available.

Key features

  • Fast recovery diode is implemented
  • Soft recovery with less ringing
  • High robustness against parasitic turn on
  • External FRD is not needed
