SC-74 Quad ESD and Surge
Protector
Surge Protection Up to 350 W Peak
Power
SMS05T1 Series
This quad monolithic silicon ESD and Surge Protector is designed
for applications requiring ESD protection. It is intended for use in
voltage and ESD sensitive equipment such as computers, printers,
business machines, communication systems and other applications.
This quad device provides superior surge protection over current quad
Zener MMQA series by providing up to 350 watts peak power.
