KRC101S-RTK from KEC Semicon, 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 | COMMON (EMITTER) | passive | Common emitter terminal of the built-in-bias NPN transistor, shared as the reference for the input and output; the datasheet gives no separate voltage or current limit for this pin. |
| 2 | IN (BASE) | input | Base input routed through the built-in bias resistor R1 (4.7 kΩ for KRC101S); the datasheet rates the KRC101S input voltage at 20 V maximum and -10 V minimum. |
| 3 | OUT (COLLECTOR) | output | Collector output of the transistor, rated at 50 V output voltage and 100 mA output current maximum for KRC101S~KRC106S. |
