1. Pulse test: t
p
< 50 ms
2. To calculate maximum clamping voltage at another 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
@ T
J
= V
BR
@ 25°C x (1 + αT x (T
J
- 25))
V
CL
@ T
J
= V
CL
@ 25°C x (1 + αT x (T
J
- 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.
