MIL-PRF-19500-394 Semiconductor Device, Transistor, Npn, Silicon, Power Switching, Types: 2N4150, 2N5237, 2N5238, 2N4150S, 2N5237S, And 2N5238S, Jan, Jantx, Jantxv, Jans, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, Jansh, Janhca, Janhcb, Jankca, Jankcb, Jankcm, Jankcd, Jankcp, Jankcl, Jankcr, Jankcf, Jankcg,And JankchThis specification covers the performance requirements for NPN, silicon, low-power, high voltage transistors. Four 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 four 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.

NOTES:

1. Dimensions are in inches.

2. Millimeters are given for general information only.

3. Beyond r (radius) maximum, TH shall be held for a minimum length of .011 (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 L1 and L2. Dimension LD applies between L2 and LL minimum. Diameter is

uncontrolled in L1 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. For 2N4150, 2N5237, and 2N5238 dimension LL shall be 1.5 inches (38.1 mm) minimum and 1.75 inches

(44.4 mm) maximum.

12. For 2N4150S, 2N5237S, and 2N5238S, dimension LL shall be .5 inch (12.7 mm) minimum and .75 inch

(19.0 mm) maximum.

13. In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.

14. Lead 1 = emitter, lead 2 = base, lead 3 = collector.
