DESCRIPTION
These high power 30 kW rated transient voltage suppressors in a surface mount package are
provided with design features to minimize thermal resistance and cumulative heating. Typical
applications include lightning and automotive load dump protection. They are particularly effective at
meeting the multi-stroke lightning standard RTCA DO-160, section 22 for aircraft design. This
efficient low profile package design is offered in standoff voltage selections (V ) of 14 volts to
WM
400 volts in either unidirectional or bidirectional construction.
