BCP52-10
Changjing · Bipolar (BJT) · SOT-223
BCP52-10 from Changjing, in a SOT-223. 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 PNP transistor (BCP52-10 is rated VCEO -60 V and IC -1 A continuous per the maximum ratings); the datasheet gives no separate pin-specific limit for the base, but base current is limited to -100 mA continuous. |
| 2 | COLLECTOR | passive | Collector terminal of the PNP transistor, rated for -1 A continuous collector current and 1.5 W collector power dissipation. |
| 3 | EMITTER | passive | Emitter terminal of the PNP transistor, rated for emitter-base voltage of -5 V. |
