SP3522-01ETG from Littelfuse, in a SOD-882. 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 cathode terminals of the cathode-to-cathode avalanche diode pair, rated for ±22kV IEC 61000-4-2 contact and air ESD, 2.5A peak pulse current (tp=8/20µs), and 7.0V reverse working voltage with 0.15pF typical capacitance. |
| 2 | 2 | passive | The other cathode terminal of the cathode-to-cathode avalanche diode pair, rated for ±22kV IEC 61000-4-2 contact and air ESD, 2.5A peak pulse current (tp=8/20µs), and 7.0V reverse working voltage with 0.15pF typical capacitance. |
