DESCRIPTION APPEARANCE
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) is packaged in an SOT - 143
configuration giving protectio n to 1 Bidirect ional 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 6100 0–4-2,
electrical fast transients (EFT ) per IEC 61000-4-4 and effects of secondary lightning.
It is also available with either Tin-Lead plated terminations or as RoHS Compliant
with annealed matte-Tin finish by adding an “e3” suffix to the part number*.
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, UNIVERSAL SERIAL BUS
(USB) and I/O transceivers. The USB504xxC product provides board level
protection from static electricity and other induced volt age surges that can damage
or upset sensitive circuitry.
