Clare, Ireland 1-800-446-1158 / (978) 620-2600 / Fax: (978) 689-0803 Tel: +353 (0) 65 6840044 Fax: +353 (0) 65 6822298 Website: http: //www.microsemi.com T4-LDS-0165 Rev. 1 (100688) Page 4 of 4 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. * FIGURE 2.
