MPLAD18KP7.0A –
MPLAD18KP200CA
Available
Surface Mount 18,000 Watt Transient Voltage Suppressor
DESCRIPTION
High-Reliability
screening available in
reference to
MIL-PRF-19500
Tested in
accordance with the
These high power 18 kW rated transient voltage suppressors in a surface mount package are
requirements of
provided with design features to minimize thermal resistance and cumulative heating.
Typical
AEC-Q101
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
WM
) of 7
volts to 200 volts in either unidirectional or bidirectional construction.
