2N2907A-338

ALJ · Bipolar (BJT) · TO-92

2N2907A-338 from ALJ, in a TO-92. 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 Emitter passive Emitter terminal of the PNP transistor; the datasheet limits emitter-base voltage VEBO to -5 V.
2 Base input Base terminal of the PNP transistor; emitter-base breakdown is -5 V minimum (IE = -10 µA) and base-emitter saturation voltage is -1 V at IC = -150 mA, IB = -15 mA.
3 Collector passive Collector terminal of the PNP transistor; limits are VCBO -60 V, VCEO -40 V, and IC -600 mA maximum.
