POWER ASSEMBLY CAPABILITY

The Power Assembly group was set up to provide a support service for those customers requiring more than the basic
semiconductor, and has developed a flexible range of heatsink and clamping systems in line with advances in device voltages
and current capability of our semiconductors.

We offer an extensive range of air and liquid cooled assemblies covering the full range of circuit designs in general use today.
The Assembly group offers high quality engineering support dedicated to designing new units to satisfy the growing needs of
our customers.

Using the latest CAD methods our team of design and applications engineers aim to provide the Power Assembly Complete
Solution (PACs).

HEATSINKS

The Power Assembly group has its own proprietary range of extruded aluminium heatsinks which have been designed to
optimise the performance of Dynex semiconductors. Data with respect to air natural, forced air and liquid cooling (with flow
rates) is available on request.

For further information on device clamps, heatsinks and assemblies, please contact your nearest sales representative or
Customer Services.

Stresses above those listed in this data sheet may cause permanent damage to the device. In extreme conditions, as with all
semiconductors, this may include potentially hazardous rupture of the package. Appropriate safety precautions should always
be followed.
