The FDPF20N50 high-voltage MOSFETs use planar stripe and DMOS technology. The FDPF20N50 MOSFET has been designed to have lower on-state resistance, improved switching performance, and a larger avalanche energy strength. Power factor correction (PFC), flat panel display (FPD) TV power, ATX, and electronic lamp ballasts are all applications for the FDPF20N50 switching power converter.
