# SK510

**DIYI Elec Tech** · Schottky Barrier Diodes (SBD) · SMB(DO-214AA)

SK510 from DIYI Elec Tech, in a SMB(DO-214AA). 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 | K | passive | Cathode, marked by the color band on the SMB package; SK510 is rated 100V maximum DC blocking voltage and 5.0A average rectified current. |
| 2 | A | passive | Anode terminal of the Schottky barrier rectifier in the SMB/DO-214AA package (forward voltage 0.85V max at IF=5.0A per the rating table). |

## CAD (KiCad official)

- Symbol: `SK510`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
- 3D model files: `sk510-etched.step` / `sk510-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk510.step` / `sk510.glb` are the bare package body.
