**Shikues** · ESD Protection Devices · SOD-523

ESD5Z7.0 from Shikues, 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 | K | passive | Cathode of the uni-directional TVS diode (marked by the band on the package), connected to the protected line; ESD5Z7.0 has 7.0 V max working reverse voltage (VRWM) and 7.5 V min breakdown at 1.0 mA. |
| 2 | A | passive | Anode of the uni-directional TVS diode, normally connected to ground; ESD5Z7.0 has 1.0 µA max reverse leakage at VRWM and 200 W peak power (8x20 µs). |

## CAD (KiCad official)

- Symbol: `ESD5Z7.0`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `esd5z7-0-etched.step` / `esd5z7-0-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd5z7-0.step` / `esd5z7-0.glb` are the bare package body.
