# 2SD880

**Changjing** · Bipolar (BJT) · TO-220-3L

2SD880 from Changjing, in a TO-220-3L. 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 | passive | Base terminal of the NPN transistor; the datasheet rates emitter-base voltage VEBO at 7 V and gives emitter-base breakdown V(BR)EBO of 7 V minimum at IE=100µA. |
| 2 | COLLECTOR | passive | Collector terminal of the NPN transistor, rated for collector-base voltage VCBO of 60 V, collector-emitter voltage VCEO of 60 V, continuous collector current IC of 3 A, and collector power dissipation PC of 1.5 W. |
| 3 | EMITTER | passive | Emitter terminal of the NPN transistor, referenced in the datasheet's emitter-base ratings (VEBO 7 V) and collector-emitter breakdown specification (VCEO 60 V). |
