PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test in accordance with method
5004 of MIL-STD-883 Class B. The verified failures (including Delta
parameters) of group A, subgroup 1, after burn-in divided by the total
number of devices submitted for burn-in in that lot shall be used to
determine the percent for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
