NOTES:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Collector shall be electrically connected to the case. This terminal may be flattened and pierced only when the
90 degree option is used.
4. SD is the outer diameter of coated threads. (Reference: Screw thread standards for Federal Standard
H28/1 , (FED-STD-H28/1).
5. The orientation of the terminals in relation to the hex flats is not controlled.
6. All three terminals.
7. The case temperature may be measured anywhere on the seating plane within .125 (3.18 mm) of the stud.
8. Terminal spacing measured at the base seat only.
9. Dimensions e, e1, PS1, and PS are measured from the center line of terminals.
10. Maximum unthreaded dimension.
11. This dimension applies to the location of the center line of the terminals.
12. A 90 degeee angle lead orientation as shown may be used at the option of the manufacturer. All dimensions
of the basic outline except e, e1, and the 120 degree lead angle apply to this option.
13. Terminal -1, emitter; terminal -2, base; terminal -3, collector.
14. A slight chamfer or undercut on one, or both, ends of the hexagonal is optional.
