What material is used in the tabs of power packages? (TO-220, D2PAK, etc.)
What material is used in the tabs of power packages? (TO-220, D2PAK, etc.) I would assume probably a tin-plated copper alloy, but I can't find a reference. Datasheets don't seem to mention the material, aside from being lead-free. See for example: - [Infineon TO-263-3](https://www.infineon.com/cms/en/product/packages/PG-TO263/PG-TO263-3-2/) - [Infineon IRF3515S](https://www.irf.com/product-info/datasheets/data/irf3515s.pdf) - [ON Semi TO-263](https://www.onsemi.com/download/package-drawing/pdf/418aj.pdf) - ON Semi [NTB60N06T4G](https://www.onsemi.com/pdf/datasheet/ntb60n06-d.pdf)
