LGE · Bipolar (BJT) · TO-92
BC547C 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 rates the emitter-base voltage VEBO at 6 V and continuous collector current IC at 100 mA. |
| 2 | BASE | input | Base terminal of the NPN transistor; VBE(sat) is 1.1 V max at IC=100 mA, IB=5 mA, and the base drives the device with the emitter-base rating VEBO of 6 V. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; for the BC547 the collector-emitter voltage VCEO is 45 V, with total device dissipation PD of 625 mW. |
