# BESD7V0D5

**BORN** · ESD And Surge Protection (TVS/ESD) · SOD-523

BESD7V0D5 from BORN, in a SOD-523. 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 (cathode band side), connected to the protected line; unidirectional TVS with 7.0 V reverse stand-off voltage and 8.0 V minimum breakdown at 1 mA. |
| 2 | A | passive | Anode, normally connected to ground; the diode clamps at 17 V at IPP = 13 A (8/20 µs). |

## CAD (KiCad official)

- Symbol: `BESD7V0D5`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `besd7v0d5-etched.step` / `besd7v0d5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `besd7v0d5.step` / `besd7v0d5.glb` are the bare package body.
