HESD9B5VDA from HXY MOSFET, in a SOD-923. 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 bidirectional ESD protection diode, which the datasheet describes as protecting one bi-directional line where arrays are not practical; the datasheet does not state which terminal is the line and which is the reference. |
| 2 | 2 | passive | The other terminal of the bidirectional ESD protection diode, rated for IEC61000-4-2 Level 4 ESD protection with a stand-off voltage of 5 V; the datasheet does not state which terminal is the line and which is the reference. |
