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 / clamping systems in line with advances in device types and the voltage 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 continues to offer high quality engineering support dedicated to designing new units to satisfy the growing needs of our
customers.
Using the up to date CAD methods our team of design and applications engineers aim to provide the Power Assembly Complete solution
(PACs).
DEVICE CLAMPS
Disc devices require the correct clamping force to ensure their safe operation. The PACs range offers a varied selection of pre-loaded
clamps to suit all of our manufactured devices. This include cube clamps for single side cooling of ‘T’ 22mm
Clamps are available for single or double side cooling, with high insulation versions for high voltage assemblies.
Please refer to our application note on device clamping, AN4839
HEATSINKS
Power Assembly has its own proprietary range of extruded aluminium heatsinks. They have been designed to optimise the performance
or our 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.

Datasheet Annotations:
Dynex Semiconductor annotate datasheets in the top right hard corner of the front page, to indicate product status. The annotations are as follows:-
Target Information: This is the most tentative form of information and represents a very preliminary specification. No actual design work on the product has been started.
Preliminary Information: The product is in design and development. The datasheet represents the product as it is understood but details may change.
Advance Information: The product design is complete and final characterisation for volume production is well in hand.
No Annotation: The product parameters are fixed and the product is available to datasheet specification.
