IXYS Introduces 600V High Power Phase Control Thyristors
IXYS Corp. announced that its UK based wholly owned subsidiary, Westcode Semiconductors Ltd., launched its new 600V thyristor range. The new thyristors are encapsulated in Westcode’s low profile Wespack housings. Four current ratings are available from 2154 to 6974A. The new devices continue IXYS’ strategic program of maximizing the power for volume and weight of its Westcode branded pressure contact thyristor products.
Frank Wakeman, Marketing & Evaluation Manager at Westcode Semiconductors, commented, "These 600V thyristors utilize a newly introduced technology developed specifically to optimize the requirements of 600V thyristors. This dedicated process results in the lowest possible forward drop at the full rated current. In combination with the unique Wespack outline, the design offers maximum current rating and lowest thermal resistance for weight and volume, without compromising on quality and reliability."
The Wespack phase control thyristor is claimed to offer a cost effective space and weight saving alternative to conventional designs, thus reducing system-size weight and cost. The Wespack thyristor package is only 14mm (0.55") thick, optimising the thermal path from silicon to cooling system. The hermetic ceramic package is suitable for all cooling options including forced air, liquid, plus total immersion systems such as oil and fluoroinert. The lower profile of the package is said to allow for a much more compact subassembly increasing realisable power for a given volume and weight.
The new options offered are: N2154JK600 (2154A, 32mm pole face with junction to case thermal resistance of 0.027 K/W); N3220QK600 (3229A, 38mm pole face with junction to case thermal resistance of 0.018 K/W); N4316MK600 (4316A, 50mm pole face with junction to case thermal resistance of 0.014 K/W); and N6974MK600 (6974A, 68mm pole face with junction to case thermal resistance of 0.009 K/W). Typical applications include welding, chemical power supplies, battery powered systems, and all low voltage rectification requirements.
