Overview
The SM12T1G is a dual monolithic silicon zener diode array 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, medical equipment, and other similar applications. The SM12T1G features a dual junction common anode design, which protects two separate lines using only one package, making it particularly useful in situations where board space is limited.
