# E2J-TD

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

E2J-TD from TDSEMIC, 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 banded/marked end per the datasheet; pad 1 of the KiCad diode footprint. |
| 2 | A | passive | Anode. |

## CAD (KiCad official)

- Symbol: `E2J-TD`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `e2j-td-etched.step` / `e2j-td-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `e2j-td.step` / `e2j-td.glb` are the bare package body.

## Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
