Changjing · Bipolar (BJT) · TO-252-2L

2SB1184 from Changjing, in a TO-252-2L. 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, with emitter-base voltage limited to -5 V (VEBO) and base-emitter saturation voltage specified at -1.2 V maximum for IC=-1.5 A, IB=-0.15 A.
2 COLLECTOR passive Collector terminal rated for -60 V collector-base voltage (VCBO), -50 V collector-emitter voltage (VCEO), and -3 A continuous collector current, with collector power dissipation of 1 W.
3 EMITTER passive Emitter terminal of the PNP transistor; the emitter-base breakdown voltage V(BR)EBO is -5 V minimum at IE=-50 µA.
