MMBT5087LT1G from onsemi, 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 low-noise transistor; the datasheet gives the device's maximum emitter-base voltage as −3.0 Vdc (VEBO) and its noise figure test conditions as the characterization context. |
| 2 | EMITTER | passive | Emitter terminal of the PNP low-noise transistor; the datasheet gives the emitter-base voltage limit VEBO of −3.0 Vdc and a maximum continuous collector current of −50 mAdc for the device. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP low-noise transistor; the datasheet gives the collector-emitter voltage limit VCEO of −50 Vdc and collector-base voltage VCBO of −50 Vdc. |
