2N50K-TA
Power MOSFET
2A, 500V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 2N50K-TA 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 2N50K-TA is generally applied in high efficiency
switch mode power supplies, active power factor correction and
electronic lamp ballasts based on half bridge topology.

FEATURES
* RDS(ON) < 4.9Ω @ VGS=10V, ID=1A
* High Switching Speed
* 100% Avalanche Tested
