MMQA, SZMMQA Quad
Common Anode Series
SC-74 Quad Monolithic
Common Anode
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.

MMQA, SZMMQA Quad Common Anode Series
TYPICAL COMMON ANODE APPLICATIONS
A quad junction common anode design in a SC-74
package protects four separate lines using only one package.
This adds flexibility and creativity to PCB design especially
when board space is at a premium. A simplified example of
MMQA/SZMMQA Series Device applications is illustrated
below.
