This specification is approved for use by all Departments
and Agencies of the Department of Defense.
The requirements for acquiring the product described herein shall consist of
this specification sheet and MIL-PRF-19500.
1. SCOPE
* 1.1 Scope. This specification covers the performance requirements for PNP, silicon, switching transistors. Five
levels of product assurance are provided for each encapsulated device type as specified in MIL-PRF-19500 and two
levels of product assurance are provided for each unencapsulated device type. Provisions for radiation hardness
assurance (RHA) to eight 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.
1.2 Phys i c al d im ens i on s . See figure 1 (similar to a TO-18), figure 2, (surface mount case outlines UA, figure 3 UB

NOTES:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Dimension "CH" controls the overall package thickness. When a window lid is used, dimension "CH" must
increase by a minimum of .010 inch (0.254 mm) and a maximum of .040 inch (1.020 mm).
4. The corner shape (square, notch, radius) may vary at the manufacturer's option, from that shown on the
drawing.
* 5. Dimensions "LW2" minimum and "L3" minimum and the appropriate castellation length define an unobstructed
three-dimensional space traversing all of the ceramic layers in which a castellation was designed.
(Castellations are required on bottom two layers, optional on top ceramic layer.) Dimension "LW2" maximum
define the maximum width and depth of the castellation at any point on its surface. Measurement of these
dimensions may be made prior to solder dipping.
6. The coplanarity deviation of all terminal contact points, as defined by the device seating plane, shall not
exceed .006 inch (0.15 mm) for solder dipped leadless chip carriers.
7. In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.

* 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 shall apply. In addition, all catastrophi c
failures during conformance inspection shall be analyzed to the extent possible to identify root cause and corrective
action. Whenever a failure is identified as wafer lot and 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.

otherwise noted.
4/ See 6.2.f herein.
5/ See method 1019, of MIL–STD–750, for how to determine [hFE] by first calculating the delta (1/hFE) from the pre-
and post-radiation hFE. Notice the [hFE] is not the same as hFE and cannot be measured directly. The [hFE]
value can never exceed the pre-radiation minimum hFE that it is based upon.

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 responsible
packaging activity.
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 Acquisition requirements. 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. The complete Part or Identifying Number (PIN), see 1.2.
e. For die acquisition, the letter version must be specified (see figures 5 and 6).
f. For acquisition of RHA designed devices, table II, subgroup 1 testing of group D is optional. If subgroup 1
testing is desired, it must be speci fied in the cont rac t.
6.3 Qualification. W ith 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 tes ted f or 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 information. Devices covered by this specification supersede the manufacturers' and users' Part
or Identifying Number (PIN). The term Part or Identifying Number (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.
