MIL-PRF-19500.  
4.5 Methods of inspection. Methods of inspection shall be as specified in the appropriate tables and as follows.  
4.5.1 Pulse measurements. Conditions for pulse measurements shall be as specified in section 4 of  
MIL-STD-750.  
4.5.2 Regulator voltage (VZ). Regulator voltage shall be measured in accordance with method 4022 of  
MIL-STD-750, except that the test shall be performed by the pulse method with tp = 0.2 ms to 300 ms. The thermal  
equilibrium requirement does not apply. For JANHC and JANKC, this measurement shall be made with the chip  
resting on a metal heat sink maintained at +25°C ±3°C. For tight tolerance C and D suffix devices, see 3.7.  
4.5.3 Voltage regulation (VZ (reg)). The breakdown voltage shall be measured at IZ = 10 percent of column 8 of  
table IV and at IZ = 50 percent of column 8 of table IV. The difference between these voltages shall then be  
determined and shall not exceed column 9 of table IV. The voltage measurement at IZ = 10 percent of column 8 of  
table IV shall be a pulse measurement in accordance with 4.5.1. The measurement at IZ = 50 percent of column 8 of  
table IV shall be made after current has been applied for 30 ±3 seconds. For this time interval, the device shall be  
suspended in free air by its leads with mounting clips with inside edge .375 inch (9.53 mm) from the body, and the  
point of connection shall be maintained at a temperature of +25°C, +8°C, -2°C. No forced air across the device shall  
be permitted. US suffix devices shall be mounted with the end caps maintained at +25°C, +8°C, -2°C. For JANHC  
and JANKC, the die shall be stabilized at +25°C and the test shall be performed utilizing pulse conditions. The VZ  
measurement may be performed after a shorter time interval following application of the test current if correlation can  
be established to the satisfaction of the Government.  
11  
MIL-PRF-19500/356H  
4.5.4 Temperature coefficient of regulator voltage (αVZ ). The device shall be temperature stabilized with current  
applied prior to reading regulator voltage at the specified ambient temperature.  
* 4.5.5 Thermal resistance. Thermal resistance (not applicable to JANHC and JANKC devices) shall be measured  
in accordance with method 3101 or 4081 of MIL-STD-750. Read and record data in accordance with 4.4.1 herein and  
shall be included in the qualification report. Forced moving air or draft shall not be permitted across the device during  
test. The maximum limit for RθJL or RθJEC under these conditions shall be specified in 1.4. The following conditions  
shall apply:  
a. IH = 2.0 A dc minimum.  
b. tH = thermal equilibrium.  
c. IM = 1 mA minimum, 10 mA maximum.  
d.  
tMD = 100 µs maximum.  
The devices shall be allowed to reach thermal equilibrium at current IH before the measurement shall be made.  
Lead spacing: LS = .375 inch (9.53 mm) for leaded devices (see figure 8).  
LS = 0 inches (end cap mount) for US suffix devices.  
4.5.6 Free-air burn-in Deliberate heat sinking, baffles to create an oven, or forced air-cooling is prohibited unless  
otherwise approved by the qualifying activity. The use of a current limiting or ballast resistors is permitted provided  
that each DUT still sees the full Pt (minimum) and that the minimum applied voltage, where applicable, is maintained  
throughout the burn-in period.  
* 4.5.7 Scope display evaluation. Scope display evaluation shall be sharp and stable in accordance with method  
4023 of MIL-STD-750. Scope display in table I, subgroup 4 shall be performed on a scope. The reverse current (IBR  
over the knee shall be 500 µA peak. Scope display may be performed on ATE (automatic test equipment) for  
screening only, with the approval of the qualifying activity.  
)
4.5.7.1 Scope display option. At the suppliers option, 100 percent scope display evaluation may be discontinued  
after three consecutive lots are 100 percent tested with zero failures. Any group A failure shall require 100 percent  
scope display to be reinvoked.  
4.5.8 Surge current (IZSM). The peak currents specified in column 10 of table III shall be applied in the reverse  
direction and shall be superimposed on the current (IZ = column 5 of table III) a total of five surges at 1 minute  
intervals. Each individual surge shall be at one-half square wave pulse of 8.3 millisecond duration or an equivalent  
sine wave with the same effective (rms) current.

5. PACKAGING  
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or  
*
order (see 6.2). When actual 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.)  
6.1 Intended use. The notes specified in MIL-PRF-19500 are applicable to this specification.  
*
6.2 Acquisition requirements. Acquisition documents should specify the following:  
a. Title, number, and date of this specification.  
b. Packaging requirements (see 5.1).  
c. Lead finish (see 3.4.2).  
d. Product assurance level and type designator.  
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  
Defense Supply Center, Columbus, ATTN: DSCC/VQE, P.O. Box 3990, Columbus, OH 43218-3990 or e-mail  
vqe.chief@dla.mil.

substitute for the looser tolerance devices (example: JANTX1N4954D substitutes for a JANTX1N4954).  
6.6 Changes from previous issue. The margins of this specification are marked with asterisks to indicate where  
changes from the previous issue were made. This was done as a convenience only and the Government assumes no  
liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the  
requirements of this document based on the entire content irrespective of the marginal notations and relationship to  
the last previous issue.
