The output power of the module should not exceed the
rated power for the module as listed in the Ordering
Information table.
Although the maximum temperature of the power modules
is TH

x

, you can limit this temperature to a lower value for

extremely high reliability.
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-Mounted
Power Modules” for a detailed discussion of thermal
aspects including maximum device temperatures.

Heat Transfer via Convection

Increased airflow over the module enhances the heat
transfer via convection. The thermal derating of figures 20
through 22 show the maximum output current that can be
delivered by each module in the indicated orientation
without exceeding the maximum TH

x

temperature versus

local ambient temperature (T

A

) for air flows of, Natural

Convection, 1 m/s (200 ft./min), 2 m/s (400 ft./min).

Layout Considerations

The EBVW020 power module series are low profile in order
to be used in fine pitch system card architectures. As such,
component clearance between the bottom of the power
module and the mounting board is limited. Avoid placing
copper areas on the outer layer directly underneath the
power module. Also avoid placing via interconnects
underneath the power module.

For additional layout guide-lines, refer to FLT007A0Z Data
Sheet.
