BC846BWQ from Yangzhou Yangjie Elec Tech, in a SOT-323. 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 | B | input | Base of the NPN transistor, drawn at the bottom left of the SOT-323 symbol; the datasheet gives V(BR)EBO of 6 V min and IEBO of 100 nA max at VEB=5V. |
| 2 | E | passive | Emitter of the NPN transistor, drawn at the bottom right of the SOT-323 symbol; the datasheet gives VEBO of 6 V. |
| 3 | C | passive | Collector of the NPN transistor, drawn on the single lead at the top of the SOT-323 symbol; for BC846BWQ the datasheet gives VCBO of 80 V, VCEO of 65 V and IC of 0.1 A continuous. |
