HESD5Z5V from HXY MOSFET, in a SOD-523. 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 terminal of the unidirectional ESD protection diode, which clamps transient events on the protected line; the datasheet gives device-level ratings (5 V stand-off, ±15 kV air and ±8 kV contact per IEC61000-4-2) but no per-pin limit or polarity. |
| 2 | 2 | passive | The other terminal of the unidirectional ESD protection diode, which clamps transient events on the protected line; the datasheet gives device-level ratings (140 W peak pulse power at 8/20 µs) but no per-pin limit or polarity. |
