MIL-PRF-19500/356L
3.6.1 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 may be used.
3.6.2 Polarity of JANHC and JANKC devices. Polarity marking is not required on JANHC or JANKC devices. All
marking shall be retained on the initial container.
3.7 Selection of tight tolerance devices. The C and D suffix devices shall be selected from JAN, JANTX, JANTXV, or
JANS devices which have successfully completed all applicable screening, and groups A, B, and C testing as ±5
percent tolerance devices. All sublots of C and D suffix devices shall pass table I, subgroup 2 at the tightened
tolerances. Tighter tolerances for mounting clip temperature shall be maintained for reference purpose to establish
correlation. For C and D tolerance levels, TA = +25°C ±2°C at .375 inch (9.53 mm) from body for leaded devices, or
zero inches for surface mount devices or equivalent.
3.8 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance
3.9 Electrical test requirements. The electrical test requirements shall be the subgroups specified in table I herein.
3.10 Maximum test ratings. Maximum test ratings for voltage regulator diodes are specified in table IV herein.
3.11 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 inspection. The inspection requirements specified herein are classified as follows:
a. Qualification inspection (see 4.2).
b. Screening (see 4.3).
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 herein 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 qualification. JANHC and JANKC qualification inspection shall be in accordance with
MIL-PRF-19500, and the specification sheet.
