Technical content
General Electric has designed this 20 Ampere rectifier specifically for the light industrial and consumer ~ low ambient temperature applications. The design utilizes the smallest practical size for the rating with Lp particular attention to rigidity and rugged construction. The solid one-piece terminal provides good Zo S mechanical strength, and minimizes breakage problems.

The entire knuHed section of the diode should be in contact with the heatsink to insure maximum heat removal. ‘A. The diode insertion force should not exceed 800 pounds, This force should be uniformly applied to the top face of the diode within an annular ring of diameter .44 > .05 inches. 5. The thermal resistance between the diode case and the heatsink will not exceed 0.5°C/W if the diode Is installed in the manner described above. : ~ 565 4F---- ee ASF — 1K
