PESD1IVN27-UX

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

PESD1IVN27-UX from Nexperia, in a SOT-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 K1 passive Cathode of diode 1 in the bidirectional ESD protection device, which clamps the protected IVN bus line (VRWM 27 V, VCL 36 V at IPP = 3 A).
2 n.c. unconnected Not connected.
3 K2 passive Cathode of diode 2 in the bidirectional ESD protection device, which clamps the protected IVN bus line (VRWM 27 V, VCL 36 V at IPP = 3 A).
