AON7458
250V,5A N-Channel MOSFET
General Description
Product Summary
The AON7458 is fabricated using an advanced high voltage
MOSFET process that is designed to deliver high levels of
performance and robustness in popular AC-DC
applications.By providing low RDS(on), Ciss and Crss along with
guaranteed avalanche capability this device can be adopted
quickly into new and existing offline power supply
designs.This device is ideal for boost converters and
synchronous rectifiers for consumer, telecom, industrial
power supplies and LED backlighting.
