# ESDU5V0H4-ES

**ElecSuper** · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

ESDU5V0H4-ES from ElecSuper, in a SOT-23-6L. 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 | IO1 | bidirectional | Connects to I/O line 1 of the protected unidirectional ESD/transient clamp channels. |
| 2 | GND | power_in | Connects to ground, the common return for the ESD protection clamps. |
| 3 | IO2 | bidirectional | Connects to I/O line 2 of the protected unidirectional ESD/transient clamp channels. |
| 4 | IO3 | bidirectional | Connects to I/O line 3 of the protected unidirectional ESD/transient clamp channels. |
| 5 | Vcc | power_in | Connects to the Vcc supply rail; the device's working voltage is stated as 5V on page 1. |
| 6 | IO4 | bidirectional | Connects to I/O line 4 of the protected unidirectional ESD/transient clamp channels. |
