USB50403C – USB50424C Bidirectional TVSarray Available DESCRIPTION This USB50403C – USB50424C Transient Voltage Suppressor (TVS) family is packaged in a SOT-143 configuration giving protection to 1 bidirectional data or interface line. It is designed for use in applications where protection is required at the board level from voltage transients caused 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 RoHS compliant versions. These TVS arrays have a peak power rating of 500 watts for an 8/20 µsec pulse. This array is suitable 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.

Total Capacitance: The total small signal capacitance between the diode terminals of a complete device. Standby Current: The current through the device at rated stand-off voltage. Breakdown Voltage: The voltage across the device at a specified current I (BR) in the breakdown region. Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an impulse current (I PP ) for a specified waveform. Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that may be continuously applied over the standard operating temperature.
