MIL-PRF-19500-290 Semiconductor Device, Transistor, Pnp, Silicon, Switching, Types, 2N2904, 2N2904A, 2N2904Al, 2N2905, 2N2905A, And 2N2905Al, Jan, Jantx, Jantxv, Jans, Jantxvm, Jantxvd, Jantxvp, Jantxvl, Jantxvr, Jantxvf, Jantxvg, Jantxvh, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, And JanshThis specification covers the performance requirements for PNP, silicon, switching transistors. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. Provision for radiation hardness assurance \(RHA\) to four radiation test levels is provided for JANTXV and JANS product assurance levels for type 2N2905A. 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. Dimension are in inches.

2. Millimeters are given for general information only.

3. Beyond r (radius) maximum, TW 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.

The device may be measured by direct methods.

7. Dimension LU applies between L1 and L2. Dimension LD applies between L2 and L minimum. Diameter is

uncontrolled in L1 and beyond LL minimum.

All three leads.

The collector shall be internally connected to the case.

10.

Dimension r (radius) applies to both inside corners of tab.

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

11.

12.

For "L" suffix devices, dimension LL is 1.50 (38.10 mm) minimum, 1.75 (44.45 mm) maximum.

13.

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