Description
These 9AF series devices are standard recovery power rectifier diodes. Mechanical design are greatly
simplified giving advantages to application.
Applications, include welders, battery chargers and general industrial current rectification.
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.
NR
Mounting - with SOLDER
Base to Heatsink
