SMS05T1 Series
SC−74 Quad Transient
Voltage Suppressor
for ESD Protection
applications requiring transient overvoltage protection capability. 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.

Typical Applications
•
Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
