The USB50403C to USB50424C TVSarray™ series is a 4-pin 1-line bidirectional ultra-low capacitance array 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. These arrays are used to protect 1 discrete line utilizing pins (1,4 signal and 2,3 ground). The S0T-143 product provides board-level protection from static electricity and other induced voltage surges that can damage sensitive circuitry. These TRANSIENT VOLTAGE SUPPRESSOR (TVS) Diode Arrays protect 3.3 Volt components such as DRAM's, SRAM's, CMOS, HCMOS, HSIC, and low voltage interfaces up to 24Volts.
