USB504 U

USB50403 – USB50424
Unidirectional TVSarray
Available
DESCRIPTION
This USB50403 – USB50424 Transient Voltage Suppressor (TVS) family is packaged in a
SOT-143 configuration giving protection to 1 unidirectional 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.

Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change in
temperature that caused it expressed in %/°C or mV/°C.
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.
