Preliminary Specification
ββββ-site
3.5.
EXPLANATION OF TEST LEVELS
1
100% production tested at +25
°C (1) (for “C” Temperature range (2) ).
2
100 % production tested at +25
°C (1), and sample tested at specified temperatures (for “V” and “M” Temperature ranges (2) ).
3
Sample tested only at specified temperatures
4
Parameter is guaranteed by design and characterization testing (thermal steady-state conditions at specified temperature).
5
Parameter is a typical value only
Only MIN and MAX values are guaranteed (typical values are issuing from characterization results).
(1) Unless otherwise specified, all tests are pulsed tests : therefore Tc = Ta where Tc and Ta are case and ambient temperature.
(2) Refer to ORDERING INFORMATION chapter.
