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. |
