MMBTSA1015 from CBI, 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 | passive | Base terminal of the PNP transistor, with base current rated to a maximum of -IB 50 mA per the absolute maximum ratings. |
| 2 | Emitter | passive | Emitter terminal of the PNP transistor, with emitter-base voltage limited to -VEBO 5 V per the absolute maximum ratings. |
| 3 | Collector | passive | Collector terminal of the PNP transistor, with collector current limited to -IC 150 mA and collector-emitter voltage to -VCEO 50 V per the absolute maximum ratings. |
