# SS510

**MDD Microdiode Semiconductor** · Schottky Diodes · SMA(DO-214AC)

SS510 from MDD Microdiode Semiconductor, in a SMA(DO-214AC). 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, the end marked by the color band; the part blocks up to 100 V (VRRM/VDC) for SS510 and carries 5.0 A average forward current. |
| 2 | A | passive | Anode, the terminal opposite the color band; forward voltage is 0.85 V maximum at 5.0 A for SS510 and peak surge current is 120 A. |

## CAD (KiCad official)

- Symbol: `SS510`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `ss510-etched.step` / `ss510-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss510.step` / `ss510.glb` are the bare package body.
