Changjing · Bipolar (BJT) · TO-92
S8550-TA from Changjing, 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 of the PNP transistor; emitter-base voltage limit is -5 V. |
| 2 | BASE | passive | Base of the PNP transistor; used to control collector current up to -0.5 A. |
| 3 | COLLECTOR | passive | Collector of the PNP transistor; collector-base -40 V, collector-emitter -25 V, continuous current -0.5 A maximum. |
