Power MOSFET
400V, 23A N-CHANNEL
POWER MOSFET
DESCRIPTION
The UTC
20N40
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
20N40
is generally applied in high efficiency switch
mode power supplies.
