STANDARD DIODES Features
High Voltage Industrial Standard Package Thick Al metal die and double stick bonding Thick copper baseplate UL E78996 approved 3500VRMS isolating voltage
ADD-A-pakTM GEN V Power Modules Benefits
Up to 1600V Full compatible TO-240AA High Surge capability Easy Mounting on heatsink Al203 DBC insulator Heatsink grounded
100 A
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. 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.
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.
