F5N50
Power MOSFET
5A, 500V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC F5N50 is an N-channel power MOSFET adopting
UTC’s advanced technology to provide customers with DMOS,
planar stripe technology. This technology is designed to meet the
requirements of the minimum on-state resistance and perfect
switching performance. It also can withstand high energy pulse in
the avalanche and communication mode.
The UTC F5N50 can be used in applications, such as active
power factor correction, high efficiency switched mode power
supplies, electronic lamp ballasts based on half bridge topology.

FEATURES
* RDS(ON) < 1.6Ω @ VGS=10V, ID=2.5A
* 100% avalanche tested
* High switching speed
