I’m looking for a transistor (or replacement) that I believe may be discontinued. GP35B60PD
Hello falk_23,
You appear to be correct as the AUIRGP35B60PD MOSFET is listed as obsolete. Ref: https://www.infineon.com/cms/en/search.html#!view=discontinued&term=GP35B60PD
One way to find a substitute is to first locate the equivalent part in the DigiKey search engine with an obsolete designation:
Near the end of the page, you will find a section for substitutions. It appears that the in-stock IXYS IXXH30N60B3D1 may be a valid substitute:
Please carefully compare data sheets specifications before substituting the component.
Best Wishes,
