3A, 500V N-CHANNEL
POWER MOSFET
DESCRIPTION
Power MOSFET
The UTC
3N50K-MK
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
3N50K-MK
is generally applied in high efficiency switch
mode power supplies, active power factor correction and electronic
lamp ballasts based on half bridge topology.
