NOTE: * 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 +.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.
