2N40K-TA
Power MOSFET
2A, 400V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC 2N40K-TA is an N-channel mode power MOSFET
using UTC’ s advanced technology to provide customers with
a minimum on-state resistance, stable off–state characteristics
and superior switching performance. It also can withstand high
energy pulse in the avalanche.
The UTC 2N40K-TA is usually used in general purpose
switching applications, motor control circuits and switched mode
power supply.

FEATURES
* High switching speed
* RDS(ON) < 2.5Ω @ VGS=10V, ID=1.25A
* 100% avalanche tested
