# MPSA94

**Foshan Blue Rocket Elec** · Bipolar (BJT) · TO-92

MPSA94 from Foshan Blue Rocket Elec, in a TO-92. 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 | Collector | passive | Collector terminal of the PNP transistor, rated for VCBO -400 V, VCEO -400 V and continuous IC -300 mA (Ta=25°C absolute maximum ratings). |
| 2 | Base | input | Base terminal that controls the PNP transistor, with an emitter-to-base voltage rating VEBO of -5.0 V. |
| 3 | Emitter | passive | Emitter terminal of the PNP transistor, with the emitter-to-base breakdown voltage limited to -5.0 V (VEBO). |

## Key specifications

| Parameter | Value |

## CAD (KiCad official)

- Symbol: `MPSA94`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92 (KiCad packages3D, STEP)
- 3D model files: `mpsa94-etched.step` / `mpsa94-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mpsa94.step` / `mpsa94.glb` are the bare package body.
