NOTES:

1. Dimensions are in inches.

2. Millimeters are given for general information only.

3. Dimension BD shall be measured at the largest diameter. The BL dimension shall include the

entire body including slugs.

4. Dimension BL shall include the sections of the lead over which the diameter is uncontrolled.

This uncontrolled area is defined as the zone between the edge of the diode body and

extending .050 inch (1.27 mm) onto the leads.

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