Power MOSFET
4 Amps, 900 Volts
N-CHANNEL MOSFET
DESCRIPTION
The UTC
4N90
is a N-channel enhancement MOSFET adopting
UTC’s advanced technology to provide customers with DMOS,
planar stripe technology. This technology is designed to meet the
requirements of the minimum on-state resistance and perfect
switching performance. It also can withstand high energy pulse in
the avalanche and communication mode.
The UTC
4N90
is particularly applied in high efficiency switch
mode power supplies.
FEATURES
* Typically 17nC low gate charge
* High switching speed
* 4A, 900V, R
DS(ON)
=4.2Ω @ V
GS
=10V
* Typically 5.6pF low C
RSS
* 100% avalanche tested
* Improved dv/dt capability
