# MMBT9013G

**ST Semtech** · Bipolar (BJT) · TO-236

MMBT9013G from ST Semtech, in a TO-236. 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 | B | input | Base terminal of the NPN transistor; VEBO maximum is 5 V and VBE is 1 V max at VCE = 1 V, IC = 100 mA. |
| 2 | E | passive | Emitter terminal of the NPN transistor; Collector current is rated up to 500 mA through the device. |
| 3 | C | passive | Collector terminal of the NPN transistor; VCBO is 40 V, VCEO is 30 V and IC is 500 mA maximum. |

## CAD (KiCad official)

- Symbol: `MMBT9013G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: TO-236 (KiCad packages3D, STEP)
- 3D model files: `mmbt9013g-etched.step` / `mmbt9013g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mmbt9013g.step` / `mmbt9013g.glb` are the bare package body.
