Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.

= 2.0W for the H10
Package.
Note 4:
If the junction temperature exceeds 150C, the output short circuit duration is 60 seconds.
Note 5:
Without a heat sink, the thermal resistance junction to ambient of the H10 Package is about 155C/W. With a heat sink, the effective thermal resistance can
only approach the junction to case values specified, depending on the efficiency of the sink.
