Low Gate Charge

Fairchild Technology's: SuperFET™, SupreMOS™, UniFET™, PowerTrench™ and FRFET®

SupreMOS® and SuperFET® FRFET® (Fast Recovery Body Diode)

Lower Qrr and Trr

Look for the "F" in the part number; e.g. FCH76N60NF

Ultra FRFET®

SiC diode is no longer needed in anti-parallel with series MOSFET and Schottky diode; while still achieving the same efficiency

Reduce Turn-on loss by 75% compared to standard MOSFETs

Reduced Qrr and Trr, compared to FRFET®, so diode switching loss is drastically reduced

Look for the "U" in the part number; e.g. FDD7N60NZU

Extensive packaging solutions

Excellent thermal performance

Excellent electrical performance
