NOTES:
1. Dimensions are in inches. Millimeters are given for general information only.
2. Measured in the zone beyond .250 (6.35 mm) from the seating plane.
3. Measured in the zone .050 (1.27 mm) and .250 (6.35 mm) from the seating plane.
4. When measured in a gauging plane .054 +.001, -.000 (1.37 +0.03, -0.00 mm) below the seating plane of
the transistor, maximum diameter leads shall be within .007 (0.18 mm) of their true location relative
to a maximum width tab. Smaller diameter leads shall fall within the outline of the maximum diameter
lead tolerance. Figure 3 shows the preferred measurement method.
5. The gate shall be electrically connected to the case.
6. Measured from the maximum diameter of the actual device.
7. All three leads. (see 3.4.1).
8. In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.
