DK5V120R15SL from Shenzhen DongKe Semicon, in a TO-252. 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 | NC | unconnected | No connect (floating); left unconnected in the application. |
| 2 | K | passive | Cathode: acts as the diode cathode in the application, and its voltage is sensed to detect operating mode and to self-power the chip when higher than A. |
| 3 | A | passive | Anode: acts as the diode anode in the application and is the reference point for the datasheet voltages (NMOS source-drain breakdown 120 V). |
