BSS63LT1G 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 transistor; the datasheet gives VBE(sat) of −900 mVdc max at IC = −25 mAdc and IB = −2.5 mAdc. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the datasheet gives an emitter-base breakdown voltage V(BR)EBO of −6.0 Vdc min at IE = −10 µAdc. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the datasheet gives VCEO of −100 Vdc and continuous collector current IC of −100 mAdc as maximum ratings. |
