To calculate maximum clamping voltage at other surge level, use the following formula: V CL max = R D x I PP + V BR max 3. To calculate V BR or V CL versus junction temperature, use the following formulas: V BR at T j = V BR at 25 C x ( + T x (T j - 25)) V CL at T j = V CL at 25 C x ( + T x (T j - 25)) Figure 3.
