General Description

This power MOSFET is produced with advanced VDMOS technology of SAMWIN.

This technology enable power MOSFET to have better characteristics, such as

fast switching time, low on resistance, low gate charge and especially excellent

avalanche characteristics. This power MOSFET is usually used at high efficient DC to

DC converter block, high efficiency switch mode power supplies, power factor

correction, electronic lamp ballast based on half bridge.
