Overview
The MMBZ6V2ALT1G is a dual monolithic silicon Zener diode produced by onsemi. It is designed for applications requiring transient overvoltage protection capability. This device is particularly useful in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment. The dual junction common anode design allows it to protect two separate lines using only one package, making it ideal for situations where board space is limited.
