SC-74 Quad Transient
Voltage Suppressor
for ESD Protection
This quad monolithic silicon voltage suppressor is designed for
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.
Features:
•SC-74 Package Allows Four Separate Unidirectional Configurations
•Peak Power – 350 Watts, 8 x 20 S
•ESD Rating of Class N (Exceeding 25 kV) per the
Human Body Model
•ESD Rating:
IEC 61000–4–2 (ESD) 15 kV (air) 8 kV (contact)
IEC 61000–4–4 (EFT) 40 Amps (5/50 ns)
IEC 61000–4–5 (lightning) 23 Amps (8/20 s)
•UL Flammability Rating of 94V–0
Typical Applications:
•Hand Held Portable Applications such as Cell Phones, Pagers,
Notebooks and Notebook Computers
