Transient Voltage Suppressors for ESD

Protection

This quad monolithic silicon voltage suppressor is designed for

applications requiring transient overvoltage protection capability. It is

intended for use in voltage and ESD sensitive equipment such as

computers, printers, business machines, communication systems,

medical equipment, and other applications. Its quad junction common

anode design protects four separate lines using only one package.

These devices are ideal for situations where board space is at a

premium.
