# SS33

**GOODWORK** · Schottky Diodes · SMA

SS33 from GOODWORK, in a SMA. 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; SS33 has 30 V maximum DC blocking voltage and 3.0 A maximum average forward rectified current. |
| 2 | A | passive | Anode, the end opposite the color band; maximum instantaneous forward voltage is 0.55 V at 3.0 A for SS32 to SS34 types. |

## CAD (KiCad official)

- Symbol: `SS33`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `ss33-etched.step` / `ss33-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss33.step` / `ss33.glb` are the bare package body.
