General Description
This Power MOSFET is produced using Winsemi’s advanced
planarstripe, VDMOS technology. This latest technology has been
especially designed to minimize on-state resistance, have a high
rugged avalanche characteristics. This devices is specially well
suited for high efficiency switch model power supplies, power factor
correction bridge and full bridge resonant topology line a and half
electronic lamp ballast.
