FMMT718TA

Diodes Incorporated · Bipolar Transistors - BJT · SOT-23

FMMT718TA 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; the datasheet pin-out shows it on the two-lead side of the package.
2 E passive Emitter of the PNP transistor; the datasheet pin-out shows it on the two-lead side of the package.
3 C passive Collector of the PNP transistor, the single lead on the opposite side of the package; rated for IC = -1.5A continuous, ICM = -6A peak, and VCEO = -20V.
