PACKAGE DIMENSIONS
NOTES:
1. Dimensions are in inches. Millimeters are given for general information only.
2. These dimensions shall be measured at points .050 inch (1.27 mm) and .055 inch (1.40 mm) below seating plane.
When gauge is not used, measurement will be made at the seating plane.
3. Two leads.
4. Collector shall be electrically connected to the case.
5. LD applies between L1 and LL maximum. Lead diameter shall not exceed twice LD within L1.
6. In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.
