To calculate VBR or VCL versus junction temperature, use the following formulas: • VBR at TJ = VBR at 25 °C x (1 + αT x (TJ - 25)) • VCL at TJ = VCL at 25 °C x (1 + αT x (TJ-25)) 2. To calculate maximum clamping voltage at other surge level, use the following formula: • VCLmax = VBR max + RD x IPPappli where IPPappli is the surge current in the application 3.
