A high voltage MOSFET family called UniFETTM MOSFET is based on DMOS and planar stripe technology. The FDP39N20 MOSFET is designed to offer superior switching performance, increased avalanche energy strength, and reduced on-state resistance. Switching power converter applications such power factor correction (PFC), flat panel display (FPD) TV power, ATX, and electronic lamp ballasts are appropriate for the FDP39N20.
