MECHANICAL DESCRIPTION
The Generation 5 of ADD-A-PAK
TM
modules combine the
excellent thermal performance obtained by the usage of
Direct Bonded Copper substrate with superior mechanical
ruggedness, thanks to the insertion of a solid copper
baseplate at the bottom side of the device. The Cu baseplate
allows an easier mounting on the majority of heatsink with
increased tolerance of surface roughness and improved
thermal spread. The Generation 5 of AAP modules is
manufactured without hard mold, eliminating in this way any
possible direct stress on the leads.
The electrical terminals are secured against axial pull-out:
they are fixed to the module housing via a click-stop feature
already tested and proved as reliable on other Vishay HPP
modules.
ELECTRICAL DESCRIPTION
These modules are intended for general purpose high
voltage applications such as high voltage regulated power
supplies, lighting circuits, temperature and motor speed
control circuits, UPS and battery charger.
