KEC Semicon · Digital Transistors · SOT-23
KRC246S-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-resistor NPN transistor; the datasheet gives no separate voltage or current limit for this pin beyond the device maximum ratings (junction temperature 150 °C, storage -55 to 150 °C). |
| 2 | IN (BASE) | input | Input (base) pin with built-in input resistor R1 (2.2 kΩ for KRC246S); the maximum input voltage for KRC246S is 12 V and -6 V, and the input-on voltage is 2.0 V max at VO=0.3 V, IO=20 mA. |
| 3 | OUT (COLLECTOR) | output | Output (collector) pin with built-in base-emitter resistor R2 (10 kΩ for KRC246S); the maximum output voltage is 50 V and the maximum output current is 800 mA, with total power dissipation rated at 200 mW. |
