IXYS Introduces a New Range of “Easy-Mount” Standard Rectifier Diode Assemblies

IXYS UK Westcode Ltd., has added a range of "easy mount" rectifier diode assemblies. The new assemblies, which can be supplied either with the diodes ready mounted or as kits, allow for easy mounting of rectifier diodes to cooling fins using four bolts. The diodes are single side mounted directly to a copper base plate pre-drilled with the four bolt holes. Diodes can be either anode or cathode side down, with three versions available suitable for 34mm to 50mm electrode devices. An extensive range of "standard" parts is available with the mounting hole positions compatible with the now obsolete range of flat based rectifiers previously offered by a number of manufacturers.

“These new clamp arrangements allow the high reliability fully hermetic capsule devices manufactured by IXYS UK to be single side mounted to cooling plates with the same ease as plastic top modules. However, the substantial copper base plate and low thermal resistance to the junction present a range of opportunities for ‘easy mount’ parts with higher current ratings than available with modules,” commented Frank Wakeman, IXYS UK’s Marketing and Technical Support Manager.

For ease of selection an extensive range of parts in three configurations are available as standard, with voltage ratings from 1.5kV to 4.5kV and average current ratings from 435A to 2035A. As an alternative, the clamps can be used with an extensive range of other IXYS UK products, including phase control thyristors, either as kits or with the devices pre-mounted. Typical applications include traction rectifiers, chemical power supplies and all general rectifier needs.
