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 NPN, 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. 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. See figure 1 (similar to TO-18), figures 2, 3, and 4 (surface mount case outlines UA,
UB, and UBC), and figures 5 and 6 (JANHC and JANKC).

NOTES:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Beyond r (radius) maximum, TL shall be held for a minimum length of .011 inch (0.28 mm).
4. Dimension TL measured from maximum HD.
5. Body contour optional within zone defined by HD, CD, and Q.
6. Leads at gauge plane .054 +.001 -.000 inch (1.37 +0.03 -0.00 mm) below seating plane shall be within .007
inch (0.18 mm) radius of true position (TP) at maximum material condition (MMC) relative to tab at MMC.
7. Dimension LU applies between L
1
and L
2
. Dimension LD applies between L
2
and LL minimum. Diameter
is uncontrolled in L
1
and beyond LL minimum.
8. All three leads.
9. The collector shall be internally connected to the case.
10. Dimension r (radius) applies to both inside corners of tab.
11. In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
12. Lead 1 = emitter, lead 2 = base, lead 3 = collector.
13. For L suffix devices, dimension LL = 1.5 inches (38.10 mm) min. and 1.75 inches (44.45 mm) max.

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 the bottom two layers, optional on the top ceramic layer.) Dimension LW2
maximum and L3 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 co-planarity deviation of all terminal contact points, as defined by the device seating plane, shall not exceed
.006 inch (0.15mm) for solder dipped leadless chip carriers.
7. In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
