KEC Semicon · Switching Diodes · SOT-23
KDS181-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 | CATHODE 1 | passive | Cathode of the first diode; the datasheet gives the pin assignment only, with no pin-specific electrical limit, and the device reverse voltage rating is VR 80 V. |
| 2 | CATHODE 2 | passive | Cathode of the second diode; the datasheet gives the pin assignment only, with no pin-specific electrical limit, and the average forward current rating is 100 mA per unit (total rating is unit rating x 1.5). |
| 3 | ANODE | passive | Common anode shared by the two diodes, as the single anode pin is listed against CATHODE 1 and CATHODE 2; the maximum (peak) forward current is 300 mA per unit and the power dissipation is 150 mW. |
