APPLICATIONS

n The DSF21545SV is a purpose designed freewheel diode to complement the DG858BW GTO in inverter circuits, using energy recovery snubbers.

FEATURES

n The DSF21545SV is designed for fast turn-on thus minimising reverse current through the GTO. n Low recovered charge for low losses. n DSF21545SV is housed in a similar outline to that of the DG858BW therefore offering complete mechanical compatibility for parallel and series clamping.

The Power Assembly group was set up to provide a support service for those customers requiring more than the basic semiconduc- tor, 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 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.
