Overview
The SZMMBZ27VCLT1G is a dual monolithic silicon zener diode produced by onsemi. This device is designed for applications requiring transient overvoltage protection and ESD (Electrostatic Discharge) protection. It is particularly suited 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 it to protect two separate lines using only one package, making it ideal for situations where board space is limited.
