# ER07D

**LGE** · Diodes - General Purpose · SOD-123FL

ER07D from LGE, in a SOD-123FL. 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 SOD-123FL body; the diode conducts when the anode is positive relative to this terminal (ER07D: VRRM 200 V, 1.0 A average forward current). |
| 2 | A | passive | Anode terminal of the rectifier, opposite the color-band end of the SOD-123FL body (ER07D: VRRM 200 V, 1.0 A average forward current). |

## CAD (KiCad official)

- Symbol: `ER07D`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `er07d-etched.step` / `er07d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `er07d.step` / `er07d.glb` are the bare package body.
