AD-BCP52
Changjing · Bipolar Transistors - BJT · SOT-223
AD-BCP52 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 of the PNP transistor; continuous base current is limited to -100 mA (peak -200 mA) and VEBO to -5 V. |
| 2 | COLLECTOR | passive | Collector of the PNP transistor; AD-BCP52 is rated VCEO -60 V and VCBO -60 V with -1 A continuous (-2 A peak) collector current. |
| 3 | EMITTER | passive | Emitter of the PNP transistor; emitter-base voltage VEBO is limited to -5 V. |
