Mounting - PRESSFIT
Use standard aluminium heatsink of minimum thickness 3 +/- 0.1 mm to obtain specified performance Drill a hole of diameter 12.65 + 0,03 mm (0,498 to 0,499 inch) in the heatsink Remove the burrs and sharp edges around the hole diameter Ensure that axis of the diodes are aligned with axis of the hole The diodes are designed for press fitted mounting from the rear side of the aluminium heatsink as indicated in the lay out figure The pressing force must be 1000 Kgs +/- 10% per diode.
Mounting - with SOLDER
