# ESD5Z5.0

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

ESD5Z5.0 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 | 1 | passive | Terminal 1 of the uni-directional TVS ESD protection diode; for ESD5Z5.0 the working peak reverse voltage (VRWM) is 5.0 V max and the breakdown voltage (VBR) is 6.2 V min at a 1.0 mA test current. |
| 2 | 2 | passive | Terminal 2 of the uni-directional TVS ESD protection diode, the other end of the same protected line; the datasheet gives the same ESD5Z5.0 limits (VRWM 5.0 V max, VBR 6.2 V min) for the device between pins 1 and 2. |

## CAD (KiCad official)

- Symbol: `ESD5Z5.0`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `esd5z5-0-etched.step` / `esd5z5-0-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd5z5-0.step` / `esd5z5-0.glb` are the bare package body.
