TJ = +150°C minimum and a minimum of PD = 75 percent of maximum rated PT
as defined in 1.3 n = 45, c = 0. The sample size may be increased and the test time
decreased as long as the devices are stressed for a tot al of 45,00 0 devi ce hours

4.4.3.3 Group C sample selection. Samples for subgroups in group C shall be chosen at random from any
inspection lot containing the intended package type and lead finish procured to the same specification which is
submitted to and passes table I tests herein for conformance inspection. When the final lead finish is solder or any
plating prone to oxidation at high temperature, the samples for C6 life test may be pulled prior to the application of
final lead finish. Testing of a subgroup using a single device type enclosed in the intended package type shall be
considered as complying with the requirements for that subgroup.
4.4.4 Gro up D inspec tion . Conformance inspection for hardness assured JANS, and JANTXV types shall include
the group D tests specified in table II herein. These tests shall be performed as required in accordance with
MIL–PRF–19500 a nd meth od 1019 of M IL-STD-750, for total ionizing dose or method 1017 of MIL-STD-750 for
neutron fluence as applicable (see 6.2 herein), except group D, subgroup 2 may be performed separate from other
subgroups. Alternate package options may also be substituted for the testing provided there is no adverse effect to
the fluence profile.
* 4.4.5 Gro up E inspe ctio n. Group E inspection shall be conducted in accordance with the conditions specified for
subgroup testing in appendix E, table E-IX of MILPRF19500 and as specified herein. Delta requirements shall be
in accordance with ta ble I, subgroup 2 and 4.5.6 herein.
4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables and as follows.
4.5.1 Input capacitance. This test shall be conducted in accordance with method 3240 of MIL-STD-750, except
the output capacitor shall be omitted.
4.5.2 Emitter to collector breakdown voltage. Method of test shall be in accordance with method 3011 of
MIL-STD-750, test condition D, except that all references to the collector and the emitter of the transistor shall be
interchanged.
4.5.3 Forward-current transfer ratio (inverted connection). Method of test shall be in accordance with method
3076 of MIL-STD-750, except that all references to the collector and the emitter of the transistor shall be
interchanged in the test circuit. Then: hFE (inv) = IE / IB
4.5.4 Emitter to collector offset voltage. The transistor shall be tested in the circuit of figure 8. The base current
shall be adjusted to the specified value. The voltage between the emitter and collector shall then be measured using
a voltmeter with an input impedance high enough that halving it does not change the measured value within the
required accuracy of the measurement.
12
MIL-PRF-19500/382K
4.5.5 Small-signal emitter-collector on-state resistance. The transistor shall be tested in the circuit of figure 9.
The base current shall be adjusted to the specified value and an ac sinusoidal signal current, Ie, of the specified rm s
value shall be applie d betw ee n the emitter and collector. The rms voltage, Vec, between the emitter and collector
shall be measured using an ac voltmeter with an input impedance high enough that halving it does not change the
measured value within the required accuracy of the measurement. The small-signal emitter-collector on-state
resistance shall then be determined as follows:
rec (on) = Vec / Ie
Where Vec is the rms voltage between the emitter and collector.

3/ Electrical characteristics apply to all device types unless otherwise noted.
4/ See 6.2.e 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 that [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.

NOTES:
1. All devices are capable of operating at TJ 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 p ower 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 desi gn curv es cho se n at T J , 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 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 Acqui sit ion requ ir e ment s. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Packaging requirements (see 5.1).
c. Lead finish (see 3.4.1).
d. The complete PIN (see 1.2 and 6.5).
e. For acquisition of RHA designed devices, table II, subgroup 1 testing of group D is optional. If subgroup 1
testing is desired, it should be spe cifi ed in th e 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 43218-3 990 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 Suppliers of JANHC and JANKC die. The qualified JANHC and JANKC suppliers with the applicable letter
version (example JANHCA2N2945) will be identified on the QML.
