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.
