**ALJ** · Bipolar (BJT) · TO-92

KSP10-061 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 | BASE | passive | Base terminal of the NPN transistor; the maximum emitter-base voltage VEBO is 3 V. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet rates the emitter-base voltage VEBO at 3 V and the continuous collector current IC at 50 mA. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the maximum ratings are VCBO 30 V, VCEO 25 V, IC 50 mA continuous, and PC 0.35 W. |
