3A, 400V N-CHANNEL

POWER MOSFET



DESCRIPTION

The UTC 3N40 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 3N40 is universally applied in electronic lamp ballast

based on half bridge topology and high efficient switched mode

power supply.
