**BORN** · ESD And Surge Protection (TVS/ESD) · 0402

0402ESDA-LP from BORN, in a 0402. 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.

## CAD (KiCad official)

- Symbol: `0402ESDA-LP`
- Footprint: `Diode_SMD:D_0402_1005Metric`
- 3D model: 0402, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal _0402_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `0402esda-lp-etched.step` / `0402esda-lp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `0402esda-lp.step` / `0402esda-lp.glb` are the bare package body.

## Provenance

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

- **Datasheet:** [BORN datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588905245267677184) (3 pp, sha256 `e1fadbc0aab1bd24`, retrieved 2026-10-09, tier: lcsc)
- **Extractor:** parts-factory `2.0.0` / `extract_pins`, primary `two-terminal convention` (convention), consensus `off` (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
- **CAD:** KiCad official libraries (CC-BY-SA 4.0).
