Overview
The SMF05T1G, produced by onsemi, is a quad monolithic silicon overvoltage suppressor designed to provide transient voltage protection. This device is particularly useful in ESD-sensitive equipment such as computers, printers, cell phones, and medical devices. It features a quad junction common anode design, allowing it to protect four separate lines using a single package, which is ideal for applications where board space is limited.
