Notes for Table 4:
1. Case temperarure is the temperature measured at the T
s
point on the substrate. Proper current derating must be observed to maintain the junction temperature below the maximum
allowable junction temperature.
2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple,” are acceptable if the following conditions are met:
– The frequency of the ripple current is 100Hz or higher
– The average current for each cycle does not exceed the maximum allowable DC forward current
– The maximum amplitude of the ripple does not exceed 20% of the maximum allowable DC forward current.
