2SC2073 from JSMSEMI, in a TO-220. 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 | Base | input | Base terminal of the NPN transistor; the datasheet gives a continuous base current rating of 0.5 A. |
| 2 | Collector | passive | Collector terminal of the NPN transistor; the datasheet gives a collector-to-base voltage of 150 V, a continuous collector current of 1.5 A, and a collector power dissipation of 25 W at Tc=25°C. |
| 3 | Emitter | passive | Emitter terminal of the NPN transistor; the datasheet gives an emitter-to-base voltage rating of 5.0 V. |
