SC−74 QUAD TRANSIENT
VOLTAGE SUPPRESSOR
24 WATTS PEAK POWER
5.6 − 33 VOLTS
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.
