Junction temperature = ambient for +25
°
C specifications.
Junction temperature = ambient at low temperature limits; junction temperature = ambient +5
°
C at high temperature limit for over temperature.
Test levels: (A) 100% tested at +25
°
C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and simulation. (C) Typical value only
for information.
(4)Current is considered positive out of node.
