BC548B 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 terminal of the NPN transistor; the datasheet limits IC continuous to 100 mA and VEBO to 6 V. |
| 2 | BASE | passive | Base terminal of the NPN transistor; VBE(sat) is specified at 1.1 V with IC=100 mA and IB=5 mA. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; for the BC548 the datasheet gives VCBO of 30 V and VCEO of 30 V, with total device dissipation of 625 mW. |
