Shenzhen DongKe Semicon · Synchronous Rectifier Controllers · TO-252

DK5V45R10SL from Shenzhen DongKe Semicon, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connect. Leave floating; not internally bonded to any functional node.
2 K passive Cathode of the equivalent rectifier. Internally the drain of the 45 V NMOS and the self-powered VCC pickup node; must stay below the 45 V V(BR)DSS in application.
3 A passive Anode of the equivalent rectifier. Internally the source of the 45 V / 10 mΩ NMOS; conducts up to 45 A continuous / 60 A peak forward current when the smart-detect logic turns the MOSFET on.
