# PMBTA92

**Nexperia** · Bipolar (BJT) · SOT-23

PMBTA92 from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Base terminal of the PNP transistor. Peak base current IBM = -100 mA (single pulse, tp ≤ 1 ms). VEBO = -5 V max. |
| 2 | E | passive | Emitter terminal of the PNP transistor. Typically connected to the positive supply rail in PNP topologies. VEBO = -5 V max. |
| 3 | C | passive | Collector terminal of the PNP transistor. VCEO = -300 V max, IC = -100 mA max (ICM = -200 mA peak). VCEsat = -500 mV max at IC = -20 mA, IB = -2 mA. |

## CAD (KiCad official)

- Symbol: `PMBTA92`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `pmbta92-etched.step` / `pmbta92-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pmbta92.step` / `pmbta92.glb` are the bare package body.
