ZX0521P from XCH(旭昌辉), 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 | TVS diode terminal 1 (bidirectional device per the page 1 symbol), protecting a data line with 5V reverse working voltage, 0.5pF max junction capacitance and ±8kV contact / 15kV air IEC 61000-4-2 ESD rating. |
| 2 | 2 | passive | TVS diode terminal 2 (bidirectional device per the page 1 symbol), connected to the other side of the protected line or to ground, with 5V reverse working voltage and 6.2V min breakdown at 1mA. |
