2. To calculate maximum clamping voltage at another 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 + αT x (TJ - 25))
V
CL @ TJ = VCL @ 25°C x (1 + αT x (TJ - 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.
