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.
Symbol LU applies between L1 and L2. Dimension LD applies between L2 and LL minimum.
Lead number three is electrically connected to case.
