Features
High Voltage
Industrial Standard Package
Thick Al metal die and double stick bonding
Thick copper baseplate
UL E78996 approved
3500VRMS isolating voltage
Benefits
Up to 1600V
Full compatible TO-240AA
High Surge capability
Easy Mounting on heatsink
Al203 DBC insulator
Heatsink grounded
Mechanical Description
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 solid
Copper baseplate at the bottom side of the device.
The Cu baseplate allow an easier mounting on the
majority of heatsink with increased tolerance of surface
roughness and improve thermal spread.
The Generation V of AAP module is manufactured
without hard mold, eliminating in this way any possible
direct stress on the leads.
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.
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 IR
modules.
