Mechanical Description
Theelectricalterminalsaresecuredagainstaxialpull-out:
they are fixed to the module housing via a click-stop
feature already tested and proved as reliable on other IR
modules.
The Generation V of Add-A-pak module combine the
excellent thermal performance obtained by the usage
of Direct Bonded Copper substrate with superior
mechanical ruggedness, thanks to the insertion of a
solidCopperbaseplateatthebottomsideofthedevice.
The Cu baseplate allow an easier mounting on the
majority of heatsink with increased tolerance of surface
roughness and improve thermal spread.
Electrical Description
These modules are intended for general purpose high
voltageapplicationssuchashighvoltageregulatedpower
supplies, lighting circuits, temperature and motor speed
control circuits, UPS and battery charger.
The Generation V of AAP module is manufactured
without hard mold, eliminating in this way any possible
direct stress on the leads.
