**TECH PUBLIC** · ESD Protection Devices · DFN1006-2

ESD5V3U1U-02LRH from TECH PUBLIC, in a DFN1006-2. 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/O | passive | Protected I/O line of the 1-line uni-directional TVS diode, with 0.3 pF typical junction capacitance to pin 2, reverse working voltage 5.3 V max and breakdown voltage 6 V min at 1 mA. |
| 2 | GND | power_in | Ground reference pin of the TVS diode, connected to the cathode side of the clamp; the datasheet labels it (GND). |

## CAD (KiCad official)

- Symbol: `ESD5V3U1U-02LRH`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `esd5v3u1u-02lrh-etched.step` / `esd5v3u1u-02lrh-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd5v3u1u-02lrh.step` / `esd5v3u1u-02lrh.glb` are the bare package body.
