See PDA Test Notes. PDA Test Notes The PDA is specified as 5% based on failures from group A, subgroup, tests after cooldown as the final electrical test in accordance with method 5 of MIL-STD-3 Class B. The verified failures of group A, subgroup, 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.
