WFF634
N-Channel MOSFET
Features
RDS(on) (Max 0.45 )@VGS=10V
Gate Charge (Typical 29nC)
Improved dv/dt Capability, High Ruggedness
www.DataSheet4U.com100% Avalanche Tested
Maximum Junction Temperature Range (150°C)
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.
