# SS54C

**MDD Microdiode Semiconductor** · Schottky Diodes · SMC(DO-214AB)

SS54C from MDD Microdiode Semiconductor, in a SMC(DO-214AB). 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 terminal, the end marked by the color band; SS54C has a maximum repetitive peak reverse voltage of 40 V and a maximum average forward rectified current of 5.0 A. |
| 2 | A | passive | Anode terminal, the end opposite the color band, where forward current enters (5.0 A maximum average forward rectified current). |

## CAD (KiCad official)

- Symbol: `SS54C`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
- 3D model files: `ss54c-etched.step` / `ss54c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss54c.step` / `ss54c.glb` are the bare package body.
