1. SCOPE
1.1 Scope. This specificatio n covers the performance requirements for NPN, silicon, switching transistors. Four
levels of product assurance (JAN, JANTX, JANTXV, and JANS) are provided for each encapsulated device type as
specified in MIL-PRF-19500, and two levels of product assurance (JANHC and JANKC) are provided for each
unencapsulated device type. 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.
1.2 Physical dimensions. The device packages for the encapsulated device types are as follows: (2N2221A and
2N2222A) (TO-18) in accordance with figure 1, (UA) in accordance with figure 2, (UB, UBC, UBN, and UBCN) in
accordance with figure 3. The dimensions and topography for JANHC and JANKC unencapsulated die is as follows:
The B version die in ac corda n ce w ith fi gure 4. The C version die in accordance w ith figure 5. The D version die in
accordance with figure 6.

MIL-PRF-19500 "Discrete Semiconductor Die/Chip Lot Acceptance". Burn-in durat ion for the JANKC lev el f ollow s
JANS requirements; the JANHC follows JANTX requirements.

applied to achieve TJ = +135°C minimum using a minimum PD = 75 percent of PT maximum, TA ambient rated as
defined in 1.3. With approva l of the qualifying activity and preparing activity, altern at e burn -in criteria (hours, bias
conditions, TJ, and mounting conditions) may be used for JANTX and JANTXV quality levels. A justification
demonstrating equivalence is required. In addition, the man u facturing site’s burn-in data and performance history will
be essential criteria for burn-in modification approval. Method 3100 of MIL-STD-750 to measure TJ shall be used.
4.3.3 Thermal impedance. The thermal impedance measurements shall be performed in accordance with method
3131 of MIL-STD-750 using the guidelines in that method for determining IM, IH, tH, tMD (and VC where appropriate).
The thermal impedance limit shall comply with the thermal impedance graph on figures 12, 13, 14, 15, and 16 (less
than or equal to the curve value at the same tH time) and sha ll be less than the pro cess determined statistica l

resubmission shall be at the test conditions of the original sample.)
Option 1: 96 hours minimum sample size in accordance with MIL-PRF-19500, table E-VIa,
adjust TA or PD to achieve TJ = +275°C min i mu m.

4.4.2.2 Group B inspection, (JAN, JANTX, and JANTXV). Separate samples may be used for each step. In the
event of a lot failure, the resubmission requirements of MIL-PRF-19500 s hall a pply. In addition, all catastr ophi c
failures during CI shall be analyzed to the extent possible to identify root cause and corrective action. Whenever a
failure is identified as wafer lot or wafer processing related, the entire wafer lot and related devices assembled from
the wafer lot shall be rejected unless an appropriate determined corrective action to eliminate the failures mode has
been implemented and the devices from the wafer lot are screened to eliminate the failure mode.

specified on this curve. Any parallel line to this curve will intersect the appropriate power for the desired
maximum TJ allowed.
2. Derate design curve constrained by the maximum junction temperature (TJ 200°C) and power rating
specified. (See 1.3 herein.)
3. Derate design curve chosen at TJ 150°C, where the maximum temperature of electrical test is performed.
4. Derate design curve chosen at TJ 125°C, and 110°C to show power rating where most users want to limit TJ
in their application.

5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or
order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these
personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging
requirements are maintained by the Inventory Control Point's packaging activities within the Military Service or
Defense Agency, or within the Military Service’s system commands. Packaging data retrieval is available from the
managing Military Department's or Defense Agency's automated packaging files, CD-ROM products, or by contacting
the responsi ble packaging acti v ity .
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.
The notes specified in MIL-PRF-19500 are applicable to this specification.)
6.1 Inten ded use. Semiconductors conforming to this specification are intended for original equipment design
applications and logistic support of existing equipment.
6.2 Acqui sit ion requ ir e ment s. Acquisition documents should specify the following:
a. Title, number, and date of this specif ica tio n.
b. Packaging requirements (see 5.1).
c. Lead finish (see 3.4.1).
d. Product assurance level and type designator.
e. For die acquisition, the JANHC or JANKC letter version shall be specified (see figures 4, 5, and 6) as well as
the RHA designer, if applicable. The JANHCA/JANKCA die version is obsolete as of the date of this revision.
Other letter versions should be used.
f. Surface mount designation if applicable.
g. For acquisition of RHA designated devices, table II, subgroup 1 testing of group D herein is optional. If
subgroup 1 is desired, it must be specified in the contract.
6.3 Qualification. With respect to products requiring qualification, awards will be made only for products which
are, at the time of award of contract, qualified for inclusion in Qualified Manufacturers List (QML 19500) whether or
not such products have actually been so listed by that date. The attention of the contractors is called to these
requirements, and manufacturers are urged to arrange to have the products that they propose to offer to the Federal
Government tested for qualification in order that they may be eligible to be awarded contracts or orders for the
products covered by this specification. Information pertaining to qualification of products may be obtained from DLA
Land and Maritime, ATTN: VQE, P.O. Box 3990, Columbus, OH 43218-3990 or e-mail vqe.chief@dla.mil. An online
listing of products qualified to this specification may be found in the Qualified Products Database (QPD) at
https://assist.dla.mil.
6.4 Supersession data. Devices covered by this specification supersede the manufacturers' and users' Part or
Identifying Number (PIN). The term PIN is equivalent to the term part number which was previously used in this
specification. This information in no way implies that manufacturers' PIN's are suitable as a substitute for the military
PIN.
