ESD5681N07-2 from WILLSEMI(Will Semicon), 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 | Pin1 | passive | Cathode of the uni-directional TVS diode (cathode marking on package); protects the power line with 7V reverse stand-off voltage (VRWM) for ESD5681N07, ±30kV IEC61000-4-2 and 27A IEC61000-4-5 rated peak pulse current. |
| 2 | Pin2 | passive | Anode of the uni-directional TVS diode, normally connected to ground; the clamping voltage of 16V at 27A (8/20μs) is measured from pin 1 to pin 2. |
