NOTES:
1 Dimension are in inches.
2 Millimeters are given for general information only.
3 Beyond r (radius) maximum, TH shall be held for a minimum length of .011 (0.28 mm).
4 Dimension TL measured from maximum HD.
5 Body contour optional within zone defined by HD, CD, and Q.
6 Leads at gauge plane .054 +.001 -.000 inch (1.37 +0.03 -0.00 mm) below seating plane shall be within .007 inch (0.18mm)
radius of true position (TP) at maximum material condition (MMC) relative to tab at MMC.
7 Dimension LU applies between L1 and L2. Dimension LD applies between L2 and LL minimum. Diameter is uncontrolled in
L1 and beyond LL minimum.
8 All four leads.
9 Dimension r (radius) applies to both inside corners of tab.
10 In accordance with ASME Y14.5M, diameters are equivalent to φx symbology.
11 Lead 1 = emitter, lead 2 = base, lead 3 = collector, lead 4 = case (electrically connected).
