# DSF1D E1D

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

DSF1D E1D from JUXING, 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 | Cathode | passive | Cathode terminal of the superfast rectifier; the datasheet gives no pin-specific electrical limits beyond the device ratings (VRRM 200 V for the DSF1D E1D family group, 1 A average forward current). |
| 2 | Anode | passive | Anode terminal of the superfast rectifier; the datasheet gives no pin-specific electrical limits beyond the device ratings. |

## CAD (KiCad official)

- Symbol: `DSF1D E1D`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `dsf1d-e1d-etched.step` / `dsf1d-e1d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dsf1d-e1d.step` / `dsf1d-e1d.glb` are the bare package body.
