Overview
The MMBZ5V6ALT1 is a dual monolithic silicon Zener diode produced by onsemi. It is designed for applications requiring transient overvoltage protection capability, making it ideal for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment. The device features a dual junction common anode design, allowing it to protect two separate lines using only one package, which is particularly beneficial when board space is limited.
