MIL-PRF-19500-495 Semiconductor Device, Unitized, Dual-Transistor, Npn, Silicon Types 2N5793, 2N5794, And 2N5793A, 2N5794A, 2N5794U, 2N5794Uc, 2N5794Au, 2N5794Auc, Jan, Jantx, Jantxv, Jans, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, And JanshScope. This specification covers the performance requirements for unitized, dual transistors which contains a pair of electrically isolated matched and unmatched NPN, silicon transistors in one package. Four levels of product assurance are provided for each device type as specified in MIL-PRF-19500. 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. Dimension "CH" controls the overall package thickness.

4. The corner shape (square, notch, radius, etc.) 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 bottom two layers, optional on 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. Lead 4 = collector.

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