To calculate VBR or VCL versus junction temperature, use the following formulas: * VBR at TJ = VBR at 25 C x (1 + T x (TJ - 25)) * VCL at TJ = VCL at 25 C x (1 + T 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.
