# SST3906T116

**ROHM Semicon** · Bipolar (BJT) · SOT-23

SST3906T116 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; VEBO is limited to -5V and the emitter-base breakdown BVEBO is -5V min at IE=-10μA. |
| 2 | B | passive | Base of the PNP transistor; the emitter cut-off current IEBO is -50nA max at VEB=-3V. |
| 3 | C | passive | Collector of the PNP transistor; rated VCEO -40V, VCBO -40V and continuous IC -200mA. |
