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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen DongKe Semicon |+| Package | TO-252 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `DK5V45R10SL`++## CAD (KiCad official)++- Symbol: `DK5V45R10SL`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shenzhen DongKe Semicon datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603108753344643072) (8 pp, sha256 `66cda6e3e9429822`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
