MMBT2907AQ

Yangzhou Yangjie Elec Tech · Bipolar (BJT) · SOT-23

MMBT2907AQ from Yangzhou Yangjie Elec Tech, 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; the datasheet drawing shows it at the bottom-left lead, and the ratings give VEBO of -5 V and VCBO of -60 V.
2 E passive Emitter of the PNP transistor, at the bottom-right lead in the drawing; the emitter-base voltage rating is -5 V.
3 C passive Collector, the single lead on top in the drawing; continuous collector current is rated at -600 mA and VCEO at -60 V.
