This 4 pin 1 line unidirectional ULTRA LOW CAPACITANCE array is designed for use in applications requiring board level protection from voltage transients caused by electrostatic discharge (ESD) as defined by IEC 1000-4-2, electrical fast transients (EFT) per IEC 1000-4-4 and effects of secondary lightning.
The document details the USB0403 thru USB0424 TVS Array Series, which are 4-pin unidirectional ultra-low capacitance devices designed for board-level protection against electrostatic discharge (ESD), electrical fast transients (EFT), and secondary lightning. These arrays protect single discrete lines utilizing pins 1 and 4 as signal inputs and pins 2 and 3 as ground connections.
