Preferred Device
Power MOSFET
20 Amps, 500 Volts
NChannel TO247
This high voltage MOSFET uses an advanced termination scheme
to provide enhanced voltageblocking capability without degrading
performance over time. In addition, this advanced Power MOSFET is
designed to withstand high energy in the avalanche and commutation
modes. The new energy efficient design also offers a draintosource
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 safe operating areas are critical
and offer additional safety margin against unexpected voltage
transients.
