SOT23 Dual Common Cathode 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
cathode design protects two separate lines using only one package.
These devices are ideal for situations where board space is at a
premium.
The MMBZ27VCLT1G/SZMMBZ27VCLT1G can be used to
protect a single wire communication network form EMI and ESD
transient surge voltages.
The MMBZ27VCLT1G/SZMMBZ27VCLT1G is recommended by
the Society of Automotive Engineers (SAE), February 2000, J2411
“Single Wire Can Network for Vehicle Applications” specification as
a solution for transient voltage problems.
