# ESD5V0J4

**Yint** · ESD Protection Devices · SOT-353

ESD5V0J4 from Yint, in a SOT-353. 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 1 | passive | Protected I/O line 1 with a TVS diode to GND, reverse stand-off voltage 5 V max, for signals above ground (unidirectional). |
| 2 | GND | power_in | Common ground return for all four TVS diodes, to be connected to ground with the shortest possible ESD return path. |
| 3 | I/O 2 | passive | Protected I/O line 2 with a TVS diode to GND, reverse stand-off voltage 5 V max, for signals above ground (unidirectional). |
| 4 | I/O 3 | passive | Protected I/O line 3 with a TVS diode to GND, reverse stand-off voltage 5 V max, for signals above ground (unidirectional). |
| 5 | I/O 4 | passive | Protected I/O line 4 with a TVS diode to GND, reverse stand-off voltage 5 V max, for signals above ground (unidirectional). |

## CAD (KiCad official)

- Symbol: `ESD5V0J4`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SOT-353 (KiCad packages3D, STEP)
- 3D model files: `esd5v0j4-etched.step` / `esd5v0j4-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd5v0j4.step` / `esd5v0j4.glb` are the bare package body.
