**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · DFN1006-2

ESD5451N-TP from TECH PUBLIC, in a DFN1006-2. 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 of two bidirectional TVS line terminals, rated for a reverse working voltage (VRWM) of 5 V max, a breakdown voltage of 5.6 V min and 8.4 V max at 1 mA, and ESD immunity to ±30 kV air and contact discharge per IEC 61000-4-2. |
| 2 | 2 | passive | The other bidirectional TVS line terminal, with the same ratings as pin 1: VRWM 5 V max, breakdown 5.6 V min to 8.4 V max at 1 mA, and ±30 kV ESD immunity per IEC 61000-4-2. |
