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 continues to offer 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).

DEVICE CLAMPS

Disc devices require the correct clamping force to ensure their safe operation. The PACS range includes a varied

selection of pre-loaded clamps to suit all of our manufactured devices. Types available include cube clamps for single

side cooling of ‘T’ 23mm and ‘E’ 30mm discs, and bar clamps right up to 83kN for our ‘Z’ 100mm thyristors and diodes.

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

The Power Assembly group has its own proprietary range of extruded aluminium heatsinks. They 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 service office.

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.
