**ROHM Semicon** · Pre-Ordered Transistors · SOT-23

BC856BHZGT116 from ROHM Semicon, 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 | E | passive | Emitter of the PNP transistor; the datasheet gives emitter-base breakdown BVEBO of -5V minimum at IE = -50uA. |
