Low Capacitance
Quad Array for
ESD Protection
LESDA6V8AV5T1G
This integrated transient voltage suppressor device (TVS) is
designed for applications requiring transient overvoltage protection. It
is intended for use in sensitive equipment such as computers, printers,
business machines, communication systems, medical equipment, and
other applications. Its integrated design provides very effective and
reliable protection for four separate lines using only one package.
These devices are ideal for situations where board space is at a
premium.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
