Suppressor
SOT–23 Dual Common Anode Zeners
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 Two Separate Unidirectional
Configurations
• Low Leakage < 1 mA @ 5 Volt
• Breakdown Voltage: 7.2–7.9 Volt @ 5 mA
• Low Capacitance (80 pF typical @ 0 Volts, 1 MHz)
• ESD Protection Meeting: 16 kV Human Body Model
ESD Protection Meeting: 30 kV Air and Contact Discharge
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
