# PESD5V0S2UAT

**Nexperia** · ESD And Surge Protection (TVS/ESD) · SOT-23

PESD5V0S2UAT from Nexperia, in a SOT-23. 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 | A1 | passive | Anode of diode 1 in the unidirectional common-cathode ESD protection pair; it protects line 1, and the datasheet measures device characteristics across pins 1 and 3. |
| 2 | A2 | passive | Anode of diode 2 in the unidirectional common-cathode ESD protection pair; it protects line 2, and the datasheet measures device characteristics across pins 2 and 3. |
| 3 | CC | passive | Common cathode shared by both ESD protection diodes; the device is rated for 30 kV contact ESD per IEC 61000-4-2 and 15 A peak pulse current at tp = 8/20 µs. |
