# ESD5Z5VU

**TECH PUBLIC** · ESD Protection Devices · SOD-523

ESD5Z5VU from TECH PUBLIC, 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 | Cathode | passive | Cathode of the uni-directional 1-line TVS diode; the reverse working voltage is 5 V max and the breakdown voltage is 6.5 V min to 9.0 V max at IT = 1 mA. |
| 2 | Anode | passive | Anode of the uni-directional TVS diode; the junction capacitance between Pin 1 and Pin 2 is 0.5 pF typical and 0.9 pF max at VR = 0 V, f = 1 MHz. |

## CAD (KiCad official)

- Symbol: `ESD5Z5VU`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `esd5z5vu-etched.step` / `esd5z5vu-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd5z5vu.step` / `esd5z5vu.glb` are the bare package body.
