NOTES:

1. Dimensions are in inches.

2. Millimeters are given for general information only.

3. Measured in the zone beyond .250 (6.35) from the seating plane.

4. Measured in the zone .050 (1.27 mm) and .250 (6.35) from the seating plane.

5. Measured from the maximum diameter of the actual case.

6. All three leads.

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

8. Lead 1 is the emitter, lead 2 is the base, and lead 3 is the collector, which is electrically connected to the

case.
