4 Amps, 500 Volts
N-CHANNEL POWER MOSFET
DESCRIPTION
The UTC
4N50
is an N-channel mode power MOSFET using
UTC’s advanced technology to provide customers with planar stripe
and DMOS technology. This technology allows a minimum on-state
resistance and superior switching performance. It also can withstand
high energy pulse in the avalanche and commutation mode.
The UTC
4N50
is generally applied in high efficiency switch mode
power supplies, active power factor correction and electronic lamp
ballasts based on half bridge topology.
