# ES2DB

**MDD Microdiode Semiconductor** · Fast Recovery / High Efficiency Diodes · DO-214AA(SMB)

ES2DB from MDD Microdiode Semiconductor, in a DO-214AA(SMB). 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 terminal, the end marked with the polarity band on the body; the package is rated for 200 V VRRM/VDC (ES2DB) and 2.0 A average forward current. |
| 2 | A | passive | Anode terminal, at the end opposite the polarity band; carries up to 2.0 A average forward current (I(AV) at TL=125°C) and 60 A peak surge (IFSM). |

## CAD (KiCad official)

- Symbol: `ES2DB`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
- 3D model files: `es2db-etched.step` / `es2db-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `es2db.step` / `es2db.glb` are the bare package body.
