Abstract

PURPOSE:To improve radiating effect by a method wherein a large radiating sheet longer than the length between two outer connecting terminals is formed on the outer connecting terminal connected to collector terminals. CONSTITUTION:A tab 1 is formed into one body with outer connecting terminals as two each of collector terminals 3 integrated with a radiating sheet 4. Both sides of radiating sheet 4 are wider than the collector terminals 3 by the width (W) making the length longer than the length (l) between the terminals 3. Thus the longer the radiating sheet 4, the larger the space thereof improving the radiating effect. In such a constitution, a package may be provided with grooves 7, 8, 9 formed on the engaging parts of package and a cavity 10 in the lead frame to improve the moisture proofing effect by means of reducing water content permeation due to improved adhesion of upper and lower resin.
