Motorola TMOS Power MOSFET Transistor Device Data
P–Channel Enhancement–Mode Silicon Gate
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 low voltage, high speed switching
applications in p ower supplies, c onverters 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.
