USB50803 thru USB50824, e3
Unidirectional Low Capacitance TVSarray ™
SCOTTSDALE DIVISION
DESCRIPTION
This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged in an SO-8
configuration’ giving protection to 2 Unidirectional data or interface lines. It is
designed for use in applications where very low capacitance 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 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*.
Using the schematic on the second page, pins 7 & 8 are tied together for the first
protected positive line, and pins 1 & 2 are tied together to the ground. The same
would then occur where pins 5 & 6 are tied together for a second protected positive
line and pins 2 & 3 are tied together to the ground. If protecting a negative line with
respect to ground, these may be switched in polarity connections where the pins are
tied together in this manner for Unidirectional protection.
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 USB508XX product provides board level protection
from static electricity and other induced voltage surges that can damage or upset
sensitive circuitry.
