1. Pulse test: t_p < 50 ms
2. To calculate maximum clamping voltage at other surge level, use the following formula: V_CLmax = V_CL - R_D x (I_PP - I_PPappli)
where I_PPappli is the surge current in the application
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 (1 + T x (T_J - 25))
V_CL at T_J = V_CL at 25 °C x (1 + T x (T_J - 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.
