Note 1ΚAll typical values except for temperature coefficient are at Ta=25к.
Note 2ΚFor conditions shown as MIN or MAX, use appropriate value under recommended operating conditions.
Note 3ΚDuration of the short -circuit should not exceed one second.
Note 4ΚStandard deviation is a measure of the statistical distribution the mean as derived from the formula:
