Overview
The SZMMBZ9V1ALT3G is a dual monolithic silicon Zener diode produced by onsemi. It is designed for applications requiring transient overvoltage protection capability and is particularly suited for use in voltage and ESD sensitive equipment. This includes devices such as computers, printers, business machines, communication systems, and medical equipment. The dual junction common anode design of the SZMMBZ9V1ALT3G allows it to protect two separate lines using only one package, making it ideal for situations where board space is limited.
