Preliminary
Power MOSFET
6 Amps, 400 Volts
N-CHANNEL POWER MOSFET
DESCRIPTION
The UTC
6N40
is an N-Channel enhancement mode Power
FET using UTC’s perfect planar stripe, DMOS technology to
provide customers with superior switching performance and
minimum on-state resistance. It also can withstand high energy
pulse in the avalanche and commutation mode.
The UTC
6N40
is generally used in applications , such as
electronic lamp ballasts based on half bridge topology and high
efficiency switched mode power supplies.
FEATURES
