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.

Configurations or a Single Bidirectional Configuration
Standard Zener Breakdown Voltage Range − 15.2 V to 16.80 V
Peak Power − 40 W @ 1.0 ms (Unidirectional),
per Figure 5 Waveform
ESD Rating:
− Class 3B (> 16 kV) per the Human Body Model
− Class C (> 400 V) per the Machine Model
ESD Rating of IEC61000−4−2 Level 4, ±30 kV Contact Discharge
Maximum Clamping Voltage @ Peak Pulse Current
Low Leakage < 5.0 mA
Flammability Rating UL 94 V−0

TYPICAL COMMON ANODE APPLICATIONS
A dual junction common anode design in a SOT−23
package protects two separate lines using only one package.
This adds flexibility and creativity to PCB design especially
when board space is at a premium. Two simplified examples
of TVS applications are illustrated below.
