MILPRF19500/427P
4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL-PRF-19500 and as specified
herein.
4.2.1 Group E qualification. Group E inspection shall be performed for qualification or re-qualification only. In
case qualification was awarded to a prior revision of the specification sheet that did not request the performance of
table II tests, the tests specified in table II herein that were not performed in the prior revision shall be performed on
the first inspection lot of this revision to maintain qualification.
4.2.2 JANHC and JANKC die. Qualification shall be in accordance with appendix G of MIL-PRF-19500 and as
specified herein.
* 4.3 Screening (JANTX, JANTXV and JANS levels only). Screening shall be in accordance with appendix E, table
E-IV of MIL-PRF-19500, and as specified herein. The following measurements shall be made in accordance with
Screening (see

(1) Thermal impedance shall be performed any time after sealing provided temperature cycling is performed in
accordance with MIL-PRF-19500, screen 3 prior to this thermal test.
* (2) For JANTX and JANTXV devices, ΔVF2 may be omitted if thermal impedance is performed, unless
irradiation is used to reduce the carrier lifetime.
(3) ZθJX is not required in screen 13, if already previously performed.
