Changjing · Bipolar (BJT) · SOT-23

2SB1198 from Changjing, in a SOT-23. 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; the datasheet gives emitter-base breakdown voltage V(BR)EBO of -5 V (IE=-50μA, IC=0).
2 EMITTER passive Emitter terminal of the PNP transistor; absolute maximum emitter-base voltage VEBO is -5 V and continuous collector current IC is -500 mA.
3 COLLECTOR passive Collector terminal of the PNP transistor; absolute maximum ratings are VCBO -80 V, VCEO -80 V, IC -500 mA continuous, and collector power dissipation PC 200 mW.
