# ES2JW

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

ES2JW from hongjiacheng, 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, the end marked by the cathode band/line on the package; ES2JW is rated 600 V VRRM and 420 V VRMS. |
| 2 | A | passive | Anode, the end opposite the cathode band; carries up to 2.0 A average forward current (50 A peak surge at 8.3 ms). |

## CAD (KiCad official)

- Symbol: `ES2JW`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `es2jw-etched.step` / `es2jw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `es2jw.step` / `es2jw.glb` are the bare package body.
