MIL-PRF-19500-355 Semiconductor Device, Unitized Dual Transistor, Npn, Silicon, Types 2N2919, 2N2920, 2N2919L, 2N2920L, 2N2919U, And 2N2920U, Jan, Jantx, Jantxv, Jans, Jansm, Jansd, Jansp, Jansl, Jansr, Jansf, Jansg, Jansh, Janhc, Janhcm, Janhcd, Janhcp, Janhcl, Janhcr, Janhcf, Janhcg, Janhch, Jankc, Jankcm, Jankcd, Jankcp, Jankcl, Jankcr, Jankcf, Jankcg, And JankchThis specification covers the performance requirements for two electrically isolated, matched NPN silicon transistors as one dual unit. 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 each unencapsulated device type die. 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:

Dimensions are in inches.

Millimeters are given for general information only.

Tab shown omitted.

Lead numbers 4 and 8 are omitted on this variation.

Beyond r maximum, TW shall be held to a minimum length of .21 inch (5.33 mm).

TL shall be measured from maximum CD.

Details of outline in this zone are optional.

CD1 shall not vary more than .010 inch (0.25 mm) in zone P. This zone is controlled for automatic

handling.

Leads at gauge plane .054 - .055 inch (1.37 - 1.40 mm) below seating plane shall be within .007 inch

(0.18 mm) radius of true position (TP) at a maximum material condition (MMC) relative to the tab at

MMC. The device may be measured by direct methods or by the gauge and gauging procedures

described on gauge drawing GS-1.

LU applies between L1 and L2. LD applies between L2 and LL minimum. Diameter is uncontrolled in

10.

L1 and beyond LL minimum.

11.

For transistor types 2N2919 and 2N2920, LL is .500 inch (12.70 mm) minimum and .750 inch (19.05

mm) maximum.

12.

For transistor type 2N2919L and 2N2920L, LL is 1.500 inches (38.10 mm) minimum and 1.750 inches (44.45

mm) maximum.

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