Note 1:
System Specification
Note 2:
Low duty cycle pulse testing techniques are used which maintain junction and case temperatures equal to the ambient temperature
Note 3:
Functionality over the –40 to 85 deg C operating temperature range is assured by design, characterization, and statistical process
