# SS210

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

SS210 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 datasheet rates the SS210 at 100 V maximum DC blocking voltage and 2.0 A average forward current. |
| 2 | A | passive | Anode, the terminal opposite the color band; the datasheet gives a maximum forward voltage of 0.85 V at 2.0 A for the SS210. |

## CAD (KiCad official)

- Symbol: `SS210`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `ss210-etched.step` / `ss210-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss210.step` / `ss210.glb` are the bare package body.
