MIN/MAX OVER TEMPERATURE
NOTES: (1) Junction temperature = ambient for +25°C specifications.
(2) Junction temperature = ambient at low temperature limit; junction temperature = ambient +9°C at high temperature limit for over temperature
specifications.
(3) 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) Not connecting the exposed slug to the –V
J
plane gives 75°C/W thermal impedance ( θ
