3. REQUIREMENTS
3.1 General. The requirements for acquiring the product described herein shall consist of this document and
MIL-PRF-19500.
3.2 Qualification. Devices furnished under this specification shall be products that are manufactured by a
manufacturer authorized by the qualifying activity for listing on the applicable qualified manufacturer's list (QML)
before contract award (see 4.2 and 6.3).
* 3.3 Abbreviations, symbols, and definitions. Abbreviations, symbols, and definitions used herein shall be as
specified in MIL-PRF-19500 and as follows.
EG - Epoxy over Glass hermetically sealed EG1 case.
3.4 Interface and physical dimensions. The interface and physical dimensions shall be as specified in
MIL-PRF-19500 and on figure 1 herein. No lead (Pb) shall be used in the construction of the die bonds.
3.4.1 Lead finish. Lead finish shall be solderable in accordance with MIL-PRF-19500, MIL-STD-750, and herein.
Where a choice of lead finish is desired, it shall be specified in the acquisition document (see 6.2).
* 3.4.2 Diode construction. These devices shall be constructed utilizing non-cavity double plug construction with
high temperature bonding between both sides of the silicon die and terminal pins. Figure 2, Epoxy-Glass (EG1 case
outline) construction for reference only.
3.5 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance
characteristics are as specified in 1.3, and table I.
3.6 Electrical test requirements. The electrical test requirements shall be the subgroups specified in 4.4.2 and
4.4.3.
3.7 Marking. Devices shall be marked as specified in MIL-PRF-19500.
Note: The EG1 version, Epoxy over Glass construction, in this specification is a construction identifier. It denotes a
type of design and not a change in package outline. . EG1 is not intended to be a package outline identifier. The
EG1 version meets all of the requirements of a non EG1 version including case outline, hermeticity, and electricals
parameters. The EG1 may be marked and shipped as a non EG1 part number because it is an equivalent device in
terms of form, fit, and function. The EG1 is interchangeable and substitutable for the non EG1 version.
3.8 Polarity. The polarity shall be indicated with a contrasting color band to denote the cathode end or the use of
other techniques considered commercial practice.
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.
