4N40
Power MOSFET
4A, 400V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 4N40 is an N-channel mode power MOSFET using
UTC’ s advanced technology to provide customers 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 4N40 is universally applied in electronic lamp ballast
based on half bridge topology and high efficient switched mode
power supply.

FEATURES
* High switching speed
* RDS(ON)<1.5Ω @ VGS=10V, ID=2A
* 100% avalanche tested
