Pulse test: tp < 50 ms 2. To calculate maximum clamping voltage at other surge level, use the following formula: VCLmax = VCL - RD x (IPP - IPPappli) where IPPappli is the surge current in the application 3. To calculate VBR or VCL versus junction temperature, use the following formulas: VBR @ TJ = VBR @ 25 C x (1 + T x (TJ - 25)) VCL @ TJ = VCL @ 25 C x (1 + T x (TJ - 25)) 4.
