# PESD36VS1UJX

**Nexperia** · ESD And Surge Protection (TVS/ESD) · SOD-323

PESD36VS1UJX 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 ESD and surge ratings are measured from pin 1 to pin 2. |
| 2 | A | passive | Anode of the unidirectional ESD protection diode, rated for 30 kV ESD (IEC 61000-4-2) and 2.5 A IPPM (8/20 µs) with the stress measured from pin 1 to pin 2. |
