SOT?23 Dual Common Anode Zeners

for ESD Protection

http://onsemi.com

These dual monolithic silicon zener diodes are designed for

applications requiring transient overvoltage protection capability. They

are intended for use in voltage and ESD sensitive equipment such as

computers, printers, business machines, communication systems,

medical equipment and other applications. Their dual junction common

anode design protects two 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.
