KEC Semicon · Digital Transistors · SOT-23
KRC102S-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 terminal, the emitter of the built-in NPN transistor with bias resistors; the datasheet states no separate electrical limit for this pin beyond the absolute maximum ratings (Ta=25°C). |
| 2 | IN (BASE) | input | Base input of the transistor, with a built-in bias resistor R1 of 10 kΩ for KRC102S; the input voltage rating for KRC102S is 30 V / -10 V. |
| 3 | OUT (COLLECTOR) | output | Collector output of the transistor, with a built-in bias resistor R2 of 10 kΩ for KRC102S; the output voltage rating is 50 V and the output current rating is 100 mA. |
