LESDA6V8AW5T1G

LESHAN RADIO COMPANY, LTD.
Low Capacitance Q uad Array for ESD Protection
General Description
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.
1. Non−repetitive current pulse per Figure 1.
2. Only 1 diode under power. For all 4 diodes under power, PD will be 25%. Mounted on FR4 board with min pad.
