USB50403 – USB50424
Available
Unidirectional TVSarray
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 effects of 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.

SYMBOLS & DEFINITIONS
Definition
Stand Off Voltage: Maximum dc voltage that can be applied over the operating temperature range.
Vwm must be selected to be equal or be greater than the operating voltage of the line to be protected.
Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current.
Clamping Voltage: Maximum clamping voltage across the TVS device when subjected to a given current at a pulse
time of 20
µs.
Standby Current: Leakage current at V
WM.
Capacitance: Capacitance of the TVS as defined @ 0 volts at a frequency of 1 MHz and stated in picofarads.
