PESD24VS1UA from Nexperia, in a SOD-323. 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 | K | passive | Cathode of the unidirectional ESD protection diode; the marking bar on the package indicates the cathode, and the diode has a 24 V reverse standoff voltage (VRWM) measured from pin 1 to pin 2. |
| 2 | A | passive | Anode of the unidirectional ESD protection diode, forming the other terminal of the protection path measured from pin 1 to pin 2 with a 24 V reverse standoff voltage (VRWM). |
