1. 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. Surge capability given for both directions for unidirectional and bidirectional types.
