# ES1DG

**Shikues** · Fast Recovery / High Efficiency Diodes · SMA

ES1DG from Shikues, in a SMA. 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 ES1AG thru ES1JG rectifier in the SMA package; the datasheet gives no separate electrical limit for this pin beyond the device ratings (50 to 600 V reverse voltage, 1 A forward current). |
| 2 | Anode | passive | Anode terminal of the ES1AG thru ES1JG rectifier in the SMA package; the datasheet gives no separate electrical limit for this pin beyond the device ratings (50 to 600 V reverse voltage, 1 A forward current). |

## CAD (KiCad official)

- Symbol: `ES1DG`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `es1dg-etched.step` / `es1dg-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `es1dg.step` / `es1dg.glb` are the bare package body.
