SP0402U-ELC-02ETG from Littelfuse, in a 0402. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IO | passive | Cathode of the unidirectional TVS diode; connect to the protected signal/data line. Clamps at 13 V typical at IPP=2.5 A (tp=8/20 µs) with 0.30 pF typical capacitance @ VR=0 V, 3 GHz. |
| 2 | GND | passive | Anode of the unidirectional TVS diode; connect to system ground. Provides the ESD discharge return path. |
