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

PESD2IVN24T-QR from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K1 | bidirectional | Cathode of first ESD protection diode with reverse stand-off voltage VRWM = 24 V and clamping voltage VCL = 33 V, connected to first automotive in-vehicle network bus line. |
| 2 | K2 | bidirectional | Cathode of second ESD protection diode with reverse stand-off voltage VRWM = 24 V and clamping voltage VCL = 33 V, connected to second automotive in-vehicle network bus line. |
| 3 | K | power_in | Common cathode connected to ground providing return path for ESD transient currents from both protection diodes. |
