# ESD5451N

**HXY MOSFET** · ESD And Surge Protection (TVS/ESD) · DFN1006-2L

ESD5451N from HXY MOSFET, in a DFN1006-2L. 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 | One terminal of the bi-directional ESD protection line; the datasheet gives a reverse working voltage VRWM of 5.0 V and a minimum reverse breakdown voltage of 5.8 V at 1 mA for the device, but no pin-specific limits are stated. |
| 2 | 2 | passive | The other terminal of the bi-directional ESD protection line; the datasheet gives IEC61000-4-2 ratings of ±30 kV for air and contact discharge for the device, but no pin-specific limits are stated. |
