# ESDVD5V0H4

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

ESDVD5V0H4 from Changjing, 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 | I/O1 | passive | ESD-protected I/O line 1, uni-directional clamp to GND with 5V reverse standoff and 2.0pF max capacitance. |
| 2 | GND | power_in | Ground reference for the TVS array; I/O and VCC clamp to this pin. |
| 3 | I/O3 | passive | ESD-protected I/O line 3, uni-directional clamp to GND with 5V reverse standoff and 2.0pF max capacitance. |
| 4 | I/O4 | passive | ESD-protected I/O line 4, uni-directional clamp to GND with 5V reverse standoff and 2.0pF max capacitance. |
| 5 | VCC | power_in | Supply-rail protection pin clamped to GND with 5V reverse standoff voltage and 5.8V min breakdown at 1mA. |
| 6 | I/O2 | passive | ESD-protected I/O line 2, uni-directional clamp to GND with 5V reverse standoff and 2.0pF max capacitance. |
