SC59 Quad Monolithic
Common Anode
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, medical equipment, and other applica-
tions. 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.
Specification Features:
SC-59 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 A
ESD Rating of Class N (exceeding 16 kV) per the Human Body Model
Mechanical Characteristics:
Void Free, Transfer-Molded, Thermosetting Plastic Case
Corrosion Resistant Finish, Easily Solderable
Package Designed for Optimal Automated Board Assembly
Small Package Size for High Density Applications
Available in 8 mm Tape and Reel
Use the Device Number to order the 7 inch/3,000 unit reel. Replace
with “T3” in the Device Number to order the 13 inch/10,000 unit reel.
