Changjing · Bipolar Transistors - BJT · TO-220F
2SD2012 from Changjing, in a TO-220F. 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 rates emitter-base voltage VEBO at 7 V and emitter-base breakdown at 7 V minimum. |
| 2 | COLLECTOR | passive | Collector terminal; the datasheet rates collector current at 3 A continuous and collector power dissipation at 2 W, with VCBO and VCEO of 60 V. |
| 3 | EMITTER | passive | Emitter terminal, referenced by the datasheet's VCEO rating of 60 V and VEBO rating of 7 V. |
