Outline Dimensions

Vishay High Power Products

DIMENSIONS FOR D2PAK in millimeters and inches

Notes

(1) Dimensioning and tolerancing per ASME Y14.5 M-1994

(2) Dimension D and E do not include mold flash. Mold flash shall not

exceed 0.127 mm (0.005") per side. These dimensions are

measured at the outmost extremes of the plastic body

(3) Thermal pad contour optional within dimension E, L1, D1 and E1

(4) Dimension b1 and c1 apply to base metal only

(5) Datum A and B to be determined at datum plane H

(6) Controlling dimension: inch

(7) Outline conforms to JEDEC outline TO-263AB
