2. Mechanical Characteristics (TO-220AB Package):

The datasheet provides a table of dimensions for the TO-220AB package, listed in both inches and millimeters. I'm not going to reproduce the full table here, as it's quite lengthy. However, it includes dimensions for:
️· A (Body Length)
️· B (Body Width)
️· C (Base to Lead Length)
️· D (Lead Length)
️· F (Lead Width)
️· G (Lead Spacing)
️· H (Body Height)
️· J (Mounting Hole Diameter)
️· K (Total Height)
️· L (Mounting Hole Distance)
️· N (Body Length)
️· Q (Lead Width)
️· R (Lead Length)
️· S (Lead Spacing)
️· T (Body Length)
️· U & V (Lead Lengths)
️· Z (Mounting Hole Distance)
