BC327-40 from LGE, 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 lead of the BC327/328 PNP transistor; the datasheet gives an emitter-base breakdown limit of VEBO = -5 V and a continuous collector current rating of -800 mA. |
| 2 | BASE | passive | Base lead of the BC327/328 PNP transistor; the datasheet gives a base-emitter saturation voltage of -1.2 V at IC = -500 mA, IB = -50 mA. |
| 3 | COLLECTOR | passive | Collector lead of the BC327/328 PNP transistor; the datasheet gives collector-emitter voltage ratings of -45 V (BC327) and -25 V (BC328) and a collector power dissipation of 625 mW. |
