**PJSEMI** · Bipolar (BJT) · SOT-23

MMBT9015C from PJSEMI, 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 terminal of the PNP transistor, where the emitter-base voltage is limited to -VEBO 5 V maximum and the emitter-base breakdown voltage is 5 V minimum at -IE = 100 μA. |
| 2 | Emitter | passive | Emitter terminal of the PNP transistor, with the absolute maximum emitter-base voltage rated at -VEBO 5 V. |
| 3 | Collector | passive | Collector terminal of the PNP transistor, rated for a maximum collector current of -IC 100 mA and a collector-emitter voltage of -VCEO 45 V. |
