12N50K-MT
Power MOSFET
12A, 500V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 12N50K-MT 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 12N50K-MT 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) < 0.52 Ω @ VGS = 10 V, ID = 6 A
* High Switching Speed
* 100% Avalanche Tested

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Drain current limited by maximum junction temperature
3. Repetitive Rating: Pulse width limited by maximum junction temperature
