NOTES:
Dimensions are in inches.
Millimeters are given for general information only.
Symbol TL is measured from HD maximum.
Details of outline in this zone are optional.
Leads at gauge plane .054 inch (1.37 mm) +.001 inch (0.03 mm) -.000 inch (0.00 mm) below seating plane shall be within
.007 inch (0.18 mm) radius of TP relative to tab. Device may be measured by direct methods or by gauge.
6 Symbol LU applies between L1 and L2. Dimension LD applies between L2 and LL minimum.
7 Lead number three is electrically connected to case.
8 Beyond r maximum, TW shall be held for a minimum length of .011 inch (0.28 mm).
9 Symbol r applied to both inside corners of tab.
10 In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
11 Lead 1 is emitter, lead 2 is base, and lead 3 is collector.
