MMBZ5V6ALT1 Series
Preferred Device
24 and 40 Watt Peak Power
Zener Transient Voltage
Suppressors
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.
Features
• Pb−Free Packages are Available
• SOT−23 Package Allows Either Two Separate Unidirectional
Configurations or a Single Bidirectional Configuration
• Working Peak Reverse Voltage Range − 3 V to 26 V
• Standard Zener Breakdown Voltage Range − 5.6 V to 33 V
• Peak Power − 24 or 40 Watts @ 1.0 ms (Unidirectional),
per Figure 5 Waveform
• ESD Rating of Class N (exceeding 16 kV) per the Human
Body Model
• Maximum Clamping Voltage @ Peak Pulse Current
• Low Leakage < 5.0 mA
• Flammability Rating UL 94 V−O

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
