描述 Description

This USB50403 – USB50424 Transient Voltage Suppressor (TVS) family is packaged in aSOT-143 configuration giving protection to 1 unidirectional data or interface line. It is designedfor use in applications where protection is required at the board level from voltage transientscaused by electrostatic discharge (ESD) as defined in IEC 61000–4-2, electrical fast transients(EFT) per IEC 61000-4-4, and secondary effects of lightning. It is also available in RoHScompliant versions.These TVS arrays have a peak power rating of 500 watts for an 8/20 ?sec pulse. This array issuitable for protection of sensitive circuitry consisting of TTL, CMOS, DRAM’s, SRAM’s,HCMOS, HSIC microprocessors, and Universal Serial Bus (USB) and I/O transceivers.
