General
The products are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling of the PKY series power modules is achieved mainly
by conduction from the baseplate to a heatsink (“cold wall”).
The PKY series power modules can also operate without a
heatsink but sufficient airflow must be provided. The Output
Current Derating graph found in the Output section for each
model provides the available output current vs. ambient air
temperature and air velocity at Vin = 53 V.
The product is tested on a 254 x 254 mm, 35 m (1 oz),
8-layer test board mounted vertically in a wind tunnel with a
cross-section of 608 x 203 mm.
For products with base plate used in a sealed box/cold wall
application, cooling is achieved mainly by conduction through
the cold wall. The Output Current Derating graphs are found in
the Output section for each model. The product is tested in a
sealed box test set up with ambient temperatures 85°C. See
Design Note 028 for further details.
Proper cooling of the product can be verified by measuring the
temperature at positions P1, P2, P3, P4 and P5. The
temperature at these positions should not exceed the max
values provided in the table below. The number of points may
vary with different thermal design and topology.
See Design Note 019 for further information.

Definition of reference temperature TP1
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum TP1,
meassured at the reference point P1 are not allowed and may
cause degradation or permanent damage to the product. TP1 is
also used to define the temperature range for normal operating
conditions. TP1 is defined by the design and used to guarantee
safety margins, proper operation and high reliability ot the
product.
