# ESDA5V3L-ES

**ElecSuper** · ESD And Surge Protection (TVS/ESD) · SOT-23

ESDA5V3L-ES from ElecSuper, in a SOT-23. 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 | IO | bidirectional | Connects to an IO line of the protected data or transmission line; the datasheet gives no further electrical limits for this pin. |
| 2 | IO | bidirectional | Connects to an IO line of the protected data or transmission line; the datasheet gives no further electrical limits for this pin. |
| 3 | GND | power_in | Connects to GND as the common return for the ESD/TVS protection clamp. |

## CAD (KiCad official)

- Symbol: `ESDA5V3L-ES`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `esda5v3l-es-etched.step` / `esda5v3l-es-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esda5v3l-es.step` / `esda5v3l-es.glb` are the bare package body.
