2SB1386 from LGE, in a SOT-89. 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 the emitter-base limit VEBO of -6 V and the emitter-base breakdown V(BR)EBO of -6 V for this device. |
| 2 | COLLECTOR | passive | Collector terminal of the PNP transistor; the datasheet limits are VCBO -30 V, VCEO -20 V and continuous collector current IC -5 A, with PC 0.5 W. |
| 3 | EMITTER | passive | Emitter terminal of the PNP transistor; the datasheet limits apply, including VCEO -20 V and emitter-base voltage VEBO -6 V. |
