SOT–223 for Surface Mount
This advanced E–FET is a TMOS Medium Power MOSFET
designed to withstand high energy in the avalanche and commutation m odes. T his n ew e nergy efficient d evice a lso offers a
drain–to–source diode with a fast recovery time. Designed for low
voltage, high speed switching applications in power supplies,
dc–dc 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
• Low R
DS(on)
— 0.15 Ω max
• The SOT–223 Package can be Soldered Using Wave or Re-
flow. The Formed Leads Absorb Thermal Stress During Soldering, Eliminating the Possibility of Damage to the Die
• Available in 12 mm Tape and Reel
Use MMFT3055ET1 to order the 7 inch/1000 unit reel.
Use MMFT3055ET3 to order the 13 inch/4000 unit reel.
