MIL-PRF-19500/429N
3.4 Interface and physical dimensions. The interface and physical dimensions shall be as specified in
MIL-PRF-19500 and on figure 1 (axial lead), figure 2 surface mount (D-5A), figures 3, and 4 (JANHC and JANKC).
3.4.1 Lead finish. Unless otherwise specified, lead or end-cap finish shall be solderable in accordance with
MIL-PRF-19500, MIL-STD-750, and herein. When solder alloy is used for finish the maximum lead temperature is
limited to 175°C maximum. Where a choice of finish is desired, it shall be specified in the acquisition document (see
6.2).
3.5 Diode construction. These devices shall be constructed utilizing non-cavity double plug construction with high
temperature metallurgical bonding between both sides of the silicon die and terminal pins. Metallurgical bonds shall
be in accordance with the requirements of category I, appendix A, MIL-PRF-19500. No point contacts are allowed.
Silver button dumet design is prohibited. US version devices shall be structurally identical to the non-surface mount
devices except for lead terminations.
3.6 Marking. Marking shall be in accordance with MIL-PRF-19500.
3.6.1 Marking of US version. For US version only, all marking except polarity indicator (see 3.6.2) may be omitted
from the body, but shall be retained on the initial container.
3.6.2 Polarity. The polarity of all types shall be indicated with a contrasting color band to denote the cathode end.
Alternatively, for US suffix devices, a minimum of three contrasting color dots spaced around the periphery on the
cathode end or a contrasting color band may be used.
3.7 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance
3.8 Electrical test requirements. The electrical test requirements shall be the subgroups specified in table I herein.
3.9 Workmanship. Semiconductor devices shall be processed in such a manner as to be uniform in quality and
shall be free from other defects that will affect life, serviceability, or appearance.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. Qualification inspection (see 4.2).
b. Screening (see 4.3).
c. Conformance inspection (see 4.4).
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 requalification 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 to 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.
