**Diodes Incorporated** · Bipolar (BJT) · SOT-23

BC807-40-7-F from Diodes Incorporated, in a SOT-23. 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; the top-view pin-out places B at the bottom left of the SOT23 body, and the part is rated for VEBO of -5.0 V and a peak base current of -200 mA. |
| 2 | E | passive | Emitter; the top-view pin-out places E at the bottom right of the SOT23 body, and the emitter-base voltage is rated at -5.0 V. |
| 3 | C | passive | Collector; the single pin on the top side of the SOT23 body, rated for VCEO of -45 V, VCBO of -50 V and continuous collector current of -0.5 A. |
