7A, 900V N-CHANNEL
POWER MOSFET
DESCRI PTI ON
The UTC 7N90 is an N-channel mode power MOSFET using
UTCs advanced technology to provide costumers with planar stripe
and DMOS technology. This technology specializes in allowing a
minimum on-state resistance and superior switching performance. It
also can withstand high energy pulse in the avalanche and
commutation mode.
The UTC 7N90 is universally applied in active power factor
correction, electronic lamp ballast based on half bridge topology and
high efficient switched mode power supply.
FEATURES
* High switching speed
* R
DS(ON)
=1.8 @ V
GS
=10V
* Typically 40nC low gate charge
* 100% avalanche tested
* Typically 17pF low C
RSS
* Improved dv/dt capability
