S9015C331

ALJ · Bipolar (BJT) · TO-92

S9015C331 from ALJ, in a TO-92. 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 Emitter passive Emitter terminal of the PNP transistor; the datasheet gives no pin-specific limit, but the device emitter-base breakdown voltage V(BR)EBO is -5 V minimum.
2 Base passive Base terminal of the PNP transistor; the datasheet gives no pin-specific limit, but base drive for saturation is specified at IB = -10 mA with IC = -100 mA.
3 C passive Collector terminal of the PNP transistor; the datasheet gives no pin-specific limit, but the device ratings are VCBO -50 V, VCEO -45 V and IC -0.1 A.
