Description

The FDPF18N50 is an UniFET™ high voltage MOSFET produced based on planar stripe and DMOS technology. It is tailored to reduce ON-state resistance and to provide better switching performance and higher avalanche energy strength. This device family is suitable for switching power converter applications such as power factor correction (PFC), flat panel display (FPD) TV power, ATX and electronic lamp ballasts.
100% Avalanche tested
45nC Typical low gate charge
25pF Typical low Crss
