General Description

This Power MOSFET is produced using Wisdom’s advanced

planar stripe, DMOS technology. This latest technology has been

especially designed to minimize on-state resistance, have a high

rugged avalanche characteristics. These devices are well suited

for high efficiency switching DC/DC converters, switch mode power

supply, DC-AC converters for uninterruped power supply, motor

control.
