# ES1JFL

**FUXINSEMI** · Fast Recovery / High Efficiency Diodes · SOD-123FL

ES1JFL from FUXINSEMI, 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 package; ES1JFL blocks up to 600V maximum repetitive peak reverse voltage. |
| 2 | A | passive | Anode; ES1JFL carries 1.0A maximum average forward rectified current at TL=75°C. |

## CAD (KiCad official)

- Symbol: `ES1JFL`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `es1jfl-etched.step` / `es1jfl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `es1jfl.step` / `es1jfl.glb` are the bare package body.
