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. |
