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 + αT x (TJ – 25)),

VCL @ TJ = VCL @ 25°C x (1 + αT x (TJ – 25))

4.

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