MIL-PRF-19500-453 Semiconductor Device, Transistor, Npn, Silicon, High-Frequency Type 2N5109 And 2N5109Ub, Jan, Jantx, Jantxv, Jans, Janhc, Jankc Jasm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, And JanshThis specification covers the performance requirements for NPN silicon, VHF-UHF amplifier transistors. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. Two levels of product assurance are provided for die. Provisions for radiation hardness assurance \(RHA\) to eight radiation levels is provided for JANS 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. This zone is controlled for automatic handling. The variation in actual diameter within this zone

shall not exceed .010 inch (0.0254 mm).

4. (Three leads) LU applies between L1 and L2. LD applies between L2 and .5 inch (12.70 mm) from

seating plane. Diameter is uncontrolled in L1 and beyond .5 inch (12.70 mm) from seating plane.

5. Measured from maximum diameter of the actual device.

6. Details of outline in this zone optional.

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