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 in the application; this lead is not internally bonded to any active node. |+| 2 | K | passive | Cathode terminal, equivalent to the cathode of a Schottky rectifier diode. Internally the drain of the integrated 45 V / 10 mΩ NMOS; self-powered VCC is derived from K when K > A. Absolute max V(BR)DSS = 45 V; VOVP threshold 10 V (ref. A). |+| 3 | A | passive | Anode terminal, equivalent to the anode of a Schottky rectifier diode. Internally the NMOS source and the chip's voltage reference (all datasheet voltages are with respect to A). Continuous current 60 A max, peak 100 A max. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen DongKe Semicon |+| Package | TO-220 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `DK5V45R10ST1`++## CAD (KiCad official)++- Symbol: `DK5V45R10ST1`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shenzhen DongKe Semicon datasheet](docs/dk5v45r10st1-datasheet.pdf) (7 pp, sha256 `031c8dd38fcefae4`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
