BC869-25 from Nexperia, in a SOT-89. 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 terminal of the PNP transistor; the device is rated for VEBO 5 V (open collector) and IC 2 A (continuous) with a peak of 3 A for single pulses up to 1 ms. |
| 2 | collector | passive | Collector terminal of the PNP transistor; the device is rated for VCEO 20 V (open base), VCBO 32 V (open emitter) and IC 2 A (continuous), and the collector is the mounting pad for the exposed heatsink on SOT89. |
| 3 | base | passive | Base terminal of the PNP transistor; the device is rated for IB 0.4 A (continuous) and IBM 0.4 A for single pulses up to 1 ms. |
