Motorola TMOS Power MOSFET Transistor Device Data
N–Channel Enhancement Mode
Silicon Gate TMOS E–FET
SOT–223 for Surface Mount
This advanced E–FET is a TMOS power MOSFET designed to
withstand high energy in the avalanche and commutation modes.
This device is also designed with a low threshold voltage so it is
fully enhanced with 5 Volts. This new energy efficient device also
offers a drain–to–source diode with a fast recovery time. Designed
for low 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. The device is
housed in the SOT–223 package which is designed for medium
power surface mount applications.

The SOT–223 Package can be Soldered Using Wave or Re-
flow. The Formed Leads Absorb Thermal Stress During Sol-
dering, Eliminating the Possibility of Damage to the Die
