# ESDA6V1L-DW

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

ESDA6V1L-DW from DOWO, 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 | I/O1 | passive | Protected line 1: uni-directional ESD clamp diode to pin 3, VRWM 5.25V max, VBR 6.1V to 7.2V at 1mA, ±16kV air / ±9kV contact per IEC 61000-4-2. |
| 2 | I/O2 | passive | Protected line 2: uni-directional ESD clamp diode to pin 3, VRWM 5.25V max, VBR 6.1V to 7.2V at 1mA, ±16kV air / ±9kV contact per IEC 61000-4-2. |
| 3 | GND | power_in | Common anode of both diodes, connected to ground as the return for ESD current (IPP 18.5A at 8/20us, clamping 16.5V max). |

## CAD (KiCad official)

- Symbol: `ESDA6V1L-DW`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `esda6v1l-dw-etched.step` / `esda6v1l-dw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esda6v1l-dw.step` / `esda6v1l-dw.glb` are the bare package body.
