BC327 from Changjing, 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 | COLLECTOR | passive | Collector terminal of the PNP transistor, rated for -800 mA continuous collector current with VCEO of -45 V (BC327) or -25 V (BC328). |
| 2 | BASE | passive | Base terminal of the PNP transistor, with emitter-base breakdown voltage VEBO of -5 V and DC current gain hFE of 100 to 630 at VCE = -1 V, IC = -100 mA. |
| 3 | EMITTER | passive | Emitter terminal of the PNP transistor, with emitter cut-off current IEBO of -0.1 uA maximum at VEB = -4 V. |
