KEXIN · Bipolar (BJT) · SOT-89
2SB1132-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; the emitter-base breakdown voltage VEBO is -5 V and the base-emitter cut-off test uses VEB = -4 V. |
| 2 | Collector | passive | Collector terminal of the PNP transistor; rated for VCBO -40 V, VCEO -32 V, and DC collector current -1 A (single pulse -2 A, PW = 100 ms). |
| 3 | Emitter | passive | Emitter terminal of the PNP transistor; the datasheet specifies VEBO -5 V as its emitter-base voltage rating. |
