GD Rectifiers offers a large selection of obsolete and hard to find components

Semiconductors by GD Rectifiers

GD Rectifiers are experts in obsolete semiconductor solutions, they can source hard to find and obsolete components, or they can re-create EOL (end of life) semiconductors.

GD Rectifiers offer assured long term component availability to customers requiring guaranteed lifetime support over the lifespan of a project by providing a unique manufacturing service of re-creating selected obsolete parts by OEMs such as IXYS, Marconi and Semikron.

GD Rectifiers’ range of obsolescence solutions are designed to help engineers, buyers and procurement specialists to continue the supply chain demand. Their comprehensive range of obsolete semiconductors include: high voltage diodes, flat based diodes, high voltage rectifiers, thyristors and fast turn-off thyristors, making GD Rectifiers the go-to source for obsolete semiconductor components

 

Thyristors

Westcode ceased production of their N260KHx, N330KHx, N350MHx and N370MHx thyristors. Today GD Rectifiers offers a modern day direct replacement thyristor with cables including: N0646LCxxx, N0910LSxxx, N1114LSxxx and N1114LSxxx.

Fast Turn-off Thyristors

GD Rectifiers offers modern day replacements for Westcode’s obsolete P300KHx and P350KHx which can now be sourced from GD Rectifiers as P1007LS12D.

GD Rectifiers understands the need for industries that have strict approval processes to have components at the ready and still in production, which is why GD Rectifiers works closely with customers to ensure component availability at all times.

High Voltage Rectifiers

GD Rectifiers offers a vast range of replacement components for obsolete high voltage rectifiers and encapsulated rectifiers previously manufactured by Marconi, IXYS (now part of Littelfuse) and Semikron. 

The following part numbers can be used as a guide to the replacements:

UGE – replaces IXYS’ high voltage rectifiers

HTZ – replaces Marconi and IXYS’ high voltage rectifiers

HSKE – replaces Semikron’s high voltage rectifiers

SKXA – replaces Semikron’s high voltage rectifiers

Obsolete Flat Based Diodes

Westcode ceased production of their SWxxHHN, SWxxHHR, SWxxKBN and SWxxKBR flat based diodes many years ago. Used by several GD Rectifiers’ customers, the company decided to re-create modern day direct replacements which can be supplied with step location washers for lead termination.

GD Rectifiers’ modern day replacements are: W0508SBxxx, W0508SBxxx, W0508RBxxx, W0438SDxxx, W0438RDxxx, W0503SDxxx, W0503RDxxx, W0628SBxxx, W0628RBxxx, W1411LCxxx, W1524LCxxx, W1748LCxxx and W2058LCxxx.

GD Rectifiers semiconductor replacement parts are manufactured to the original manufacturer’s design specifications, or equivalents and are a modern day replacement. GD Rectifiers offers custom design and manufacture to meet specific requirements of customers in the commercial, industrial, medical, automotive, aerospace and rail industries. 

By providing specialist obsolescence support, GD Rectifiers is able to enhance customers design flexibility within their builds by extending the lifecycle of their projects, particularly in industries where strict approval processes have to be undertaken in order for components to be accepted in to a company or build. These obsolescence solutions save customers a lot of time and money by preventing them from having to source new components frequently.
