Product Summary

FDA28N50 is a Fairchild Semiconductors high voltage MOSFET family based on planar stripe and DMOS technology. This MOSFET 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. The applications include PDP TV, uninterruptible Power Supply and AC-DC Power Supply.
