Overview
The SZMMBZ15VDLT1G is a dual monolithic silicon zener diode produced by onsemi, designed for applications requiring transient overvoltage protection capability. These devices are ideal for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment. The dual junction common cathode design allows for the protection of two separate lines using only one package, making them particularly useful in situations where board space is limited.
