In order to make this ESCC 5201/002 consistent with the requirements specified in MIL-PRF-19500/255, as both ESCC & MIL components use the same semiconductor die and hence are effectively the same component, the following additional changes are included in this DCR:
Note: ST have confirmed that none of the following changes would results in any negative impact on the ESCC qualification or on the customers' use of these ESCC components.
A) Removal of the non-QPL Variants 06, 07, 09 & 10 in all places (Paras 1.4.2, 1.5, 1.7, 2.4.1, 2.9.2).
B) For the ESCC qualified variants (01, 02, 04, 05, 11, 12), in order to be consistent with MIL-PRF-19500/255, the following changes shall apply:
1) Para 2.4.1, The IC current test condition for V(BR)CEO is changed to IC = 10mA (was 30mA)
2) Para 2.4.1, The Small-Signal Forward-Current Transfer Ratio limit /hfe/ = changed to 2.5 min (was 3 min to 10 max)
3) Para 2.4.1 Note 1, The pulse measurement conditions changed to pulse width ≤ 25ms (was ≤ 300µs)
Note – The ESCC qualification certificate #233 currently states VCEO = 40V for 2N2222A. This will need to be amended to 50V once this DCR has been approved.
