2SB1260-R from Slkor(SLKORMICRO Elec.), 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 of the PNP transistor; emitter-base voltage is limited to -5 V (VEBO) and IEBO is max -1 μA at VEB=-4V. |
| 2 | EMITTER | passive | Emitter of the PNP transistor; V(BR)EBO is min -5 V at IE=-50μA. |
| 3 | COLLECTOR | passive | Collector of the PNP transistor (also the tab); VCEO and VCBO are -80 V, IC is -1 A DC and -2 A pulse. |
