MultiGuard
(2 & 4 Elements)
AVX Multilayer Ceramic
Transient Voltage Suppression Arrays
ESD Protection for CMOS and Bi Polar Systems
GENERAL DESCRIPTION AND COMMENTS
AVX’s Transient Voltage Suppression (TVS) Arrays address
six trends in today’s electronic circuits: (1) mandatory ESD
protection, (2) mandatory EMI control, (3) signal integrity
improvement, (4) PCB downsizing, (5) reduced component
placement costs, and (6) protection from induced slow
speed transient voltages and currents.
AVX’s MultiGuard products offer numerous advantages,
which include a faster turn-on-time (<1nS), repetitive strike
capability, and space savings. In some cases, MultiGuard
consumes less than 75% of the PCB real estate required for
the equivalent number of discrete chips. This size advantage,
coupled with the savings associated with placing only one
chip, makes MultiGuard the TVS component of choice for
ESD protection of I/O lines in portable equipment and pro-
gramming ports in cellular phones. Other applications
include differential data line protection, ASIC protection and
LCD driver protection for portable computing devices.
Where multiple lines require the ESD protection, the 4-element
0612 or 0508 chip is an ideal solution. While the 2-element
0405 MultiGuard is the smallest TVS array, the 4-element
0508 MultiGuard is the smallest 4-element TVS device avail-
able in the market today.
Available with standard working voltage of 5.6V up to 18V
with low capacitance in the 3 case sizes, AVX MultiGuard
arrays offer a very broad range of integrated TVS solutions
to the design community.
