PESD12VS2UT

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

PESD12VS2UT 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 K1 passive Cathode of diode 1; device ratings and Cd are measured from pin 1 or 2 to pin 3, with VRWM 12 V max and Cd 38 pF typ, 75 pF max at 1 MHz, VR = 0 V.
2 K2 passive Cathode of diode 2; device ratings and Cd are measured from pin 1 or 2 to pin 3, with VRWM 12 V max and Cd 38 pF typ, 75 pF max at 1 MHz, VR = 0 V.
3 A passive Common anode shared by both diodes; the reference for all ratings, with peak pulse power 180 W and ESD up to 30 kV (IEC 61000-4-2 contact) stated for pin 1 or 2 to pin 3.
