2SB1386-R from KEXIN, 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 | passive | Base terminal of the PNP transistor, with emitter-base breakdown voltage BVEBO of -6 V minimum and VEBO rated at -6 V, and base drive of IB = -0.1 A used in the VCE(sat) test at IC = -4 A. |
| 2 | Collector | passive | Collector terminal, rated for IC = -5 A continuous and ICP = -10 A single pulse (Pw = 10 ms), with VCBO = -30 V and VCEO = -20 V, and PC = 0.5 W. |
| 3 | Emitter | passive | Emitter terminal of the PNP transistor, with emitter-base voltage VEBO rated at -6 V. |
