1 / 6 page © Semiconductor Components Industries, LLC, 2005 August, 2005 − Rev. 6 1 Publication Order Number: MMQA/D MMQA Quad Common Anode Series Preferred Devices SC−74 Quad Monolithic Common Anode Transient Voltage Suppressors 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, medical equipment, and other applications. Its quad junction common anode design protects four separate lines using only one package. These devices are ideal for situations where board space is at a premium. Features • SC−74 Package Allows Four Separate Unidirectional Configurations • Peak Power − Min. 24 W @ 1.0 ms (Unidirectional), per Figure 5 Waveform • Peak Power − Min. 150 W @ 20 ms (Unidirectional), per Figure 6 Waveform • Maximum Clamping Voltage @ Peak Pulse Current • Low Leakage < 2.0 mA • ESD Rating of Class N (exceeding 16 kV) per the Human Body Model • Pb−Free Packages are Available THERMAL CHARACTERISTICS (TA = 25°C unless otherwise noted) Characteristic Symbol Value Unit Peak Power Dissipation @ 1.0 ms (Note 1) @ TA ≤ 25°C Ppk 24 W Peak Power Dissipation @ 20 ms (Note 2) @ TA ≤ 25°C Ppk 150 W Total Power Dissipation on FR-5 Board (Note 3) @ TA = 25°C °PD° °225 1.8 mW ° mW/ °C ° Thermal Resistance from Junction−to−Ambient RqJA 556 °C/W Total Power Dissipation on Alumina Substrate (Note 4) @ TA = 25°C Derate above 25 °C °PD° °300 2.4 mW ° mW/ °C Thermal Resistance from Junction−to−Ambient RqJA 417 °C/W Junction and Storage Temperature Range TJ, Tstg °− 55 to +150 ° °C Lead Solder Temperature − Maximum (10 Second Duration) TL 260 °C SC−74 QUAD TRANSIENT VOLTAGE SUPPRESSOR 24 WATTS PEAK POWER 5.6 − 33 VOLTS Preferred devices are recommended choices for future use and best overall value.
