9N50K-MT
Power MOSFET
9A, 500V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 9N50K-MT is an N-channel mode power MOSFET
using UTC’s advanced technology to provide customers planar
stripe and DMOS technology. This technology allows a minimum
on-state resistance, superior switching performance. It also can
withstand high energy pulse in the avalanche and commutation
mode.
The UTC 9N50K-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) < 0.85Ω @ VGS = 10 V, ID = 4.5 A
* High Switching Speed
* Improved dv/dt Capability
* 100% Avalanche Tested
