# B772S

**Shikues** · Bipolar (BJT) · SOT-23

B772S from Shikues, 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 | BASE | input | Base of the PNP transistor; absolute maximum base current is -0.6 A and emitter-base voltage is -5 V. |
| 2 | EMITTER | passive | Emitter of the PNP transistor; emitter-base breakdown voltage is -5 V minimum at IE = -1 mA. |
| 3 | COLLECTOR | passive | Collector of the PNP transistor; VCEO is -30 V, VCBO is -40 V, continuous collector current is -3 A (peak -7 A at t = 10 ms). |

## CAD (KiCad official)

- Symbol: `B772S`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `b772s-etched.step` / `b772s-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `b772s.step` / `b772s.glb` are the bare package body.
