4 Amps, 900 Volts N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 4N90Z 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 4N90Z is particularly applied in high efficiency switch
mode power supplies.

FEATURES
* RDS(ON) < 2.2Ω @ VGS=10V, ID=2A
* High switching speed
* 100% avalanche tested
* Improved dv/dt capability
