shall not exceed 0.127 mm (0.005") per side. These dimensions
are measured at the outermost extremes of the plastic body
Dimension b1, b3 and c1 apply to base metal only
Controlling dimensions: inches
Dimensions E2 x H1 define a zone where stamping and
singulation irregularities are allowed
Outline conforms to JEDEC TO-220, except A2 (maximum) and
D2 (minimum) where dimensions are derived from the actual
