Preferred Device
Power MOSFET
1 Amp, 60 Volts
P–Channel SOT–223
This Power MOSFET is designed to withstand high energy in the
avalanche and commutation modes. 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.
Silicon Gate for Fast Switching Speeds
The SOT–223 Package can be Soldered Using Wave or Reflow. The
Formed Leads Absorb Thermal Stress During Soldering, Eliminating
the Possibility of Damage to the Die
