BORN · Digital Transistors · SOT-23
KRC103S from BORN, 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 | Input pin to the built-in bias resistor network (R1 = 22 kΩ); the absolute maximum input voltage range is -10 V to 40 V. |
| 2 | Emitter | passive | Common emitter pin, with the built-in bias resistor R2 = 22 kΩ in the base-emitter path; the datasheet gives no separate voltage or current limit for this pin. |
| 3 | Collector | output | Output collector pin; the absolute maximum output voltage is 50 V and the maximum output current is 100 mA. |
