Limiting element voltage
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70
°
C
.
The voltage rating is calculated by the following equation.
If the value obtained exceeds the limiting element voltage,
the voltage rating is equal to the maximum operating voltage.
