Whisker Test Report Product Covered Commercial SiC Schottky Rectifiers, Commercial SiC Junction Transistors and Modules Co-pack in the DO-214 (SMB), TO-252, TO-220, and TO-247 package. See page 2 for part numbers covered by this report. Issue Date February 16, 2016 Issued by GeneSiC Semiconductor, Inc. This is to report the whisker test result conducted by GeneSiC Semiconductor over all SMB and TO products manufactured in GeneSiC Semiconductor plant. Test is executed based on JEDEC JESD201A, per its table 4a and 4c, except preconditioning A was substituted by preconditioning B. Test result summary Three production lots were selected to represent all SMB and TO products manufactured by GeneSiC Semiconductor plant. Outside lead plating is 100% Sn, Matte-Tin plating with whisker mitigation per JEDEC JP002. This plating process is common to all SMB and TO products. Sample preparation and preconditioning, and also stress tests and whisker measurements were done by GeneSiC Semiconductor. Test result successfully satisfied requirements of Class 1, 1A and 2 per JEDEC JESD201 table 5a. The solder reflow profile used is shown on figure 1.
