Overview
The MMBZ15VALT1G is a dual monolithic silicon Zener diode designed by onsemi for applications requiring transient overvoltage protection. These devices are intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment. The dual junction common anode design allows for the protection of two separate lines using only one package, making them ideal for situations where board space is limited.
