NOTES:
1. Dimensions are in inches. Metric equivalents 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 +.3, -.00 mm) before the seating plane of
the transistor, maximum diameter leads shall be within .007 (.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.
5. The active elements are electrically insulated from the case.
6. All 4 leads.
7. Lead 1 is the source, lead 2 is the drain, lead 3 is the gate, and lead 4 is the case.
8. Symbol TL is measured from HD maximum.
9. In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
