# ES3D-SMB

**GOODWORK** · Fast Recovery/High Efficiency Diode · SMB(DO-214AA)

ES3D-SMB from GOODWORK, 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 package; the ES3D blocks up to 200 V DC and passes 3.0 A average forward current. |
| 2 | A | passive | Anode terminal, the end opposite the cathode color band; the ES3D has a maximum forward voltage of 1.0 V at 3.0 A. |

## CAD (KiCad official)

- Symbol: `ES3D-SMB`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
- 3D model files: `es3d-smb-etched.step` / `es3d-smb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `es3d-smb.step` / `es3d-smb.glb` are the bare package body.
