NOTES: (1) 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. (2) Junction temperature = ambient for 25
°C guaranteed specifications. (3) Junction temperature = ambient at low temperature
limit: junction temperature = ambient +23
°C at high temperature limit for over temperature guaranteed specifications. (4) Current is considered positive out of node. V
