MIL-PRF-19500-391 Semiconductor Device, Transistor, Npn, Silicon, Low-Power Types 2N3019, 2N3019S, 2N3057A, 2N3700, And 2N3700Ub, Jan, Jantx, Jantxv, Jantxvm, Jantxvd, Jantxvp, Jantxvl, Jantxvr, Jantxvf, Jantxvg, Jantxvh Jans, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, Jansh, Janhca, Janhcb, Jankca, Jankcb Jankcbm, Jankcd, Jankcp, Jankcl, Jankcr, Jankcf, Jankcg, And JankchThis specification covers the performance requirements for NPN, silicon, low-power transistors. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. Two levels of product assurance are provided for the unencapsulated device type 2N3700. Provisions for radiation hardness assurance \(RHA\) to three radiation levels is provided for JANTXV JANS, JANHC, and JANKC product assurance levels. Radiation hardness assurance \(RHA\) level designators "M", "D", "P", "L", "R", "F", "G" and "H" are appended to the device prefix to identify devices, which have passed RHA requirements.

3.5 Radiation hardness assurance (RHA). Radiation hardness assurance requirements, PIN designators, and test

levels shall be as defined in MIL�PRF�19500.

3.6 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance

characteristics are as specified in 1.3, 1.4, and table I.

3.7 Electrical test requirements. The electrical test requirements shall be as specified in table I.

3.8 Marking. Marking shall be in accordance with MIL�PRF�19500, except for the UB suffix package. Marking on

the UB package shall consist of an abbreviated part number, the date code, and the manufacturers symbol or logo.

The prefixes JAN, JANTX, JANTXV, and JANS can be abbreviated as J, JX, JV, and JS respectively. The "2N" prefix

can also be omitted. The radiation hardened designator M, D, P, L, R, F, G, or H shall immediately precede (or

replace) the device "2N" identifier (depending upon degree of abbreviation required).

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 and tables I, II, and III).

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 III tests, the tests specified in table III 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 qualification. JANHC and JANKC qualification inspection shall be in accordance with
