2SB1132-R

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.
