FMMT717TA

Diodes Incorporated · Bipolar Transistors - BJT · SOT-23

FMMT717TA from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base of the PNP transistor; drive current is limited by the IB rating of -500mA and VEBO of -7V.
2 E passive Emitter of the PNP transistor, which sees a maximum emitter-base voltage of -7V relative to the base.
3 C passive Collector of the PNP transistor (VCEO -12V, IC -2.5A continuous, ICM -10A peak), which also serves as the thermal lead.
