Transient Voltage Suppressors
for ESD Protection
These dual monolithic silicon zener diodes are designed for applications
requiring transient overvoltage protection capability. They are intended for use
in voltage and ESD sensitive equipment such as computers, printers, business
machines, communication systems, medical equipment and other applications.
Their dual junction common anode design protects two separate lines using
only one package. These devices are ideal for situations where board space is
at a premium.
Specification Features:
• SOT–23 Package Allows Either Two Separate Unidirectional
Configurations or a Single Bidirectional Configuration
• Peak Power — 24 or 40 Watts @ 1.0 ms (Unidirectional),
per Figure 5 Waveform
• Maximum Clamping Voltage @ Peak Pulse Current
• Low Leakage < 5.0 µA
• 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
the “T1” with “T3” in the Device Number to order the 13 inch/10,000 unit reel.
