CONTROLLING DIMENSIONS ARE IN MILLIMETERS (mm).
(DIMENSIONING AND TOLERANCING CONFORMS TO ANSI Y14.5M-1982)
PIN 1 IDENTIFIER FOR REVERSE PIN OUT (DIE UP).
PIN 1 IDENTIFIER FOR REVERSE PIN OUT (DIE DOWN), INK OR LASER MARK.
TO BE DETERMINED AT THE SEATING PLANE -C- . THE SEATING PLANE IS DEFINED AS THE PLANE OF
CONTACT THAT IS MADE WHEN THE PACKAGE LEADS ARE ALLOWED TO REST FREELY ON A FLAT
HORIZONTAL SURFACE.
DIMENSIONS D1 AND E DO NOT INCLUDE MOLD PROTRUSION. ALLOWABLE MOLD PROTUSION IS
0.15mm (.0059") PER SIDE.
DIMENSION b DOES NOT INCLUDE DAMBAR PROTUSION. ALLOWABLE DAMBAR PROTUSION SHALL BE
0.08 (0.0031") TOTAL IN EXCESS OF b DIMENSION AT MAX. MATERIAL CONDITION. MINIMUM SPACE
BETWEEN PROTRUSION AND AN ADJACENT LEAD TO BE 0.07 (0.0028").
THESE DIMENSIONS APPLY TO THE FLAT SECTION OF THE LEAD BETWEEN 0.10MM (.0039") AND
0.25MM (0.0098") FROM THE LEAD TIP.
LEAD COPLANARITY SHALL BE WITHIN 0.10mm (0.004") AS MEASURED FROM THE SEATING PLANE.
DIMENSION "e" IS MEASURED AT THE CENTERLINE OF THE LEADS.
