Diodes, Dual 40 Watt Peak
Power, High Temperature
SC−70 Dual Common Anode Zeners
MMBZHxxVAWT1G Series,
SZMMBZHxxVAWT1G Series
www.onsemi.com
These dual monolithic silicon Zener diodes are designed for
applications requiring transient overvoltage ESD 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 high temperature rated and ideal for use in high reliability
applications where board space is at a premium.
