PACKAGE DIMENSIONS
NOTES:
1. Terminal 1, emitter; terminal 2, base; terminal 3, collector; terminal 4, case.
2. Chamfer or undercut on one or both ends of hexagonal portion is optional.
3. The outline contour with the exception of the hexagon is optional within cylinder defined by CD1 and A1.
4. Terminal r can be flattened and pierced or hook type. A visual index is required when the flattened and pierced tab
terminal contour (identical to the adjacent terminals) option is used. The case terminal (hook) is mechanically connected
to the case. The other three terminals shall be electrically isolated from the case.
5. Angular orientation of terminals with respect to hexagon is optional.
6. HT dimension does not include sealing flanges.
7. SU is the length of incomplete or undercut threads.
8. SD is the pitch diameter of coated threads. Reference: Screw threads standards for Federal Service Handbook H28, part I.
9. Dimensions are in inches.
10. Millimeters are giving for general information only.
11. In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.

NOTES:
1. Dimensions are in inches. Millimeters are given for general information only
2. Collector shall be electrically connected to the case. This terminal may be flattened and pierced only when the 90 degree
option is used.
3. SD is the pitch diameter of coated threads. Reference: Screw thread standards for Federal Service Handbook H28, part I.
4. The orientation of the terminals in relation to the hex flats is not controlled.
5. All three terminals.
6. The case temperature may be measured anywhere on the seating plane within .125 (3.18 mm) of the stud.
7. Terminal spacing measured at the base seat only.
8. Dimensions PS, PS1, PS2, and PS3 are measured from the centerline of terminals.
9. Maximum unthreaded dimension.
10. This dimension applies to the location of the center line of the terminals.
11. A 90 degree angle lead orientation as shown may be used at the option of the manufacturer. All dimensions of the basic
outline except PS, PS1, and the 120lead angle apply to this option.
12. Terminal 1, emitter; terminal 2, base; terminal 3, collector.
13. A slight chamfer or undercut on one or both ends of the hexagonal is optional.
14. In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.
