Overview
The MMQA5V6T1G is a quad monolithic silicon voltage suppressor designed by onsemi for applications requiring transient overvoltage protection. This component is part of the MMQA and SZMMQA Quad Common Anode Series and is housed in an SC-74 package. It is intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment. The quad junction common anode design allows it to protect four separate lines using a single package, making it ideal for situations where board space is limited.
