# ESDA6V8UE

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

ESDA6V8UE from TECH PUBLIC, in a SOT-23-6. 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 | ESD-protected I/O line (IEC 61000-4-2 ±25kV air, ±20kV contact), VRWM 5V max to ground, 0.3pF typical I/O to I/O. |
| 2 | GND | power_in | Ground reference pin of the TVS array, connected to the anode of the central diode and the lower steering-diode rail. |
| 3 | I/O2 | passive | ESD-protected I/O line (IEC 61000-4-2 ±25kV air, ±20kV contact), VRWM 5V max to ground, 0.3pF typical I/O to I/O. |
| 4 | I/O3 | passive | ESD-protected I/O line (IEC 61000-4-2 ±25kV air, ±20kV contact), VRWM 5V max to ground, 0.3pF typical I/O to I/O. |
| 5 | VCC | power_in | Upper steering-diode rail connected to the cathode of the central TVS diode; clamping is specified up to 15V max at Ipp=10A (8/20us) from VCC pin to ground. |
| 6 | I/O4 | passive | ESD-protected I/O line (IEC 61000-4-2 ±25kV air, ±20kV contact), VRWM 5V max to ground, 0.3pF typical I/O to I/O. |

## CAD (KiCad official)

- Symbol: `ESDA6V8UE`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `esda6v8ue-etched.step` / `esda6v8ue-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esda6v8ue.step` / `esda6v8ue.glb` are the bare package body.
