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 pre­loaded 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 it’s 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 the
factory.

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.

This publication is issued to provide information only which (unless agreed by the Company in writing) may not be used, applied or reproduced for any purpose nor form part of any order or contract nor to be regarded as
a representation relating to the products or services concerned. No warranty or guarantee express or implied is made regarding the capability, performance or suitability of any product or service. The Company reserves
the right to alter without prior notice the specification, design or price of any product or service. Information concerning possible methods of use is provided as a guide only and does not constitute any guarantee that such
methods of use will be satisfactory in a specific piece of equipment. It is the user's responsibility to fully determine the performance and suitability of any equipment using such information and to ensure that any publication
or data used is up to date and has not been superseded. These products are not suitable for use in any medical products whose failure to perform may result in significant injury

or death to the user. All products and materials are sold and services provided subject to the Company's conditions of sale, which are available on request.
