N–Channel Enhancement–Mode Silicon Gate
TMOS POWER FET
20 AMPERES
500 VOL TS
This high voltage MOSFET uses an advanced termination
scheme to provide enhanced voltage–blocking capability without

degrading performance over time. In addition, this advanced TMOS
E–FET is designed to withstand high energy in the avalanche and
commutation modes. The new energy efficient design also offers a
drain–to–source diode with a fast recovery time. Designed for high
voltage, high speed switching applications in power supplies,
converters and PWM motor controls, these devices are particularly
well suited for bridge circuits where diode speed and commutating
D
safe operating areas are critical and offer additional safety margin
against unexpected voltage transients.
