PESD12VS1UA

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

PESD12VS1UA 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 K1 passive Cathode of the unidirectional TVS diode, identified by the marking band, connected to the protected signal line (VRWM 12 V max, VBR 13.3 V to 15.75 V at IR = 5 mA).
2 A passive Anode of the unidirectional TVS diode, connected to ground (GND) in the application diagram for positive signal polarity lines.
