LMBT6520LT1G from LRC, 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 high-voltage transistor, with base current rated at -250 mA (maximum, per the absolute maximum ratings). |
| 2 | EMITTER | passive | Emitter terminal of the PNP high-voltage transistor; emitter-base breakdown V(BR)EBO is -5.0 Vdc minimum and the emitter cutoff current is tested at V(EB) = -4.0 V. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP high-voltage transistor, rated for a continuous collector current of -500 mAdc with V(CEO) of -350 Vdc. |
