Note 7: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals −55˚C), then testing immediately
without allowing for the junction temperature to stabilize due to heat dissipation after power-up. This provides “cold start” specs which can be considered a worst case
condition at cold temperatures.
Note 8: Screen tested 100% on each device at +25˚C, Temperature only, Subgroup A9.
Note 9: Sample tested (Method 5005, Table I) on each Mfg. lot at +25˚C, Subgroup A9, and at +125˚C, and −55˚C Temperature, Subgroups A10 and A11.
Note 10: Not tested at +25˚C, +125˚C and −55˚C Temperature (design characterization data).
