FMMTA92QTA

Diodes Incorporated · Bipolar (BJT) · SOT-23

FMMTA92QTA 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; Emitter-Base voltage limit is -5V (VEBO) and base-emitter saturation voltage is at most -0.9V at IC = -20mA, IB = -2mA.
2 E passive Emitter of the PNP transistor; emitter-base breakdown voltage is at least -5V at IE = -100µA.
3 C passive Collector of the PNP transistor; VCEO and VCBO are -300V maximum and continuous collector current is -200mA.
