0402ESDA-18N

BORN · ESD And Surge Protection (TVS/ESD) · 0402

0402ESDA-18N from BORN, in a 0402. 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 A passive Anode/cathode terminal A of bi-directional polymer ESD suppressor; working voltage 18 V, trigger voltage 100 V typ, clamping voltage 50 V typ (65 V typ / 100 V max per IEC 61000-4-2 Level 4), capacitance 1.5 pF typ / 3 pF max at 1 MHz, leakage <1 nA.
2 B passive Anode/cathode terminal B of bi-directional polymer ESD suppressor; electrically equivalent to pin 1 - device is fully symmetric with no polarity.
