MMBZxxxAL Series
Common Anode Zeners for ESD Protection
SOT-23 Plastic-Encapsulate Anode Zeners for ESD Protection Diodes
DESCRIPTION
The 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 ideal for situations where board space is at a premium.
Features
SOT-23 package allows either two separate
unidirectional configurations or a single
bidirectional configuration.
Working peak reverse voltage 3V to 22V
Standard Zener breakdown voltage 5.6V to 27V
Peak power 24 or Watts @ 1.0ms (unidirectional)
per Figure 6 Waveform
ESD Rating:
Class 3B (>16kV) per the Human Body Model
Class C (>400V) per Machine Model
ESD Rating:
ESD Rating of IEC61000-4-2 level 4, ±30kV
contact Discharge
Low leakage < 5.0uA
Meets MSL 1 Requirements
