LITTELFUSE

Our Surface Mount Power Device (SMPD) packaging technology is an expansion of the ISOPLUS™ package portfolio to include modules that can be assembled in standard surface mount (SMD) soldering processes and is pick-and-place ready to be assembled on a customer’s existing SMD assembly lines. Our SMPD range provides a large array of standard options in terms of topology or silicon varieties. Its simplicity and optimized manufacturing process enables fast time to market for customers that require differing die and circuit combinations effectively fast tracking product development. Numerous discrete devices can be successfully combined in one high reliability package that can then be easily assembled on current SMD assembly lines.

Weighing only 8g, the SMPD package is much lighter (typically by 50%) than comparable conventional power modules, thereby enabling lower weight power systems. Due to its compact and ultra-low profile package, it is possible to use the same heat sink for multiple devices, saving PCB space. An added benefit of being smaller and lighter is that it provides better protection against vibrations and g-forces, especially if used in portable appliances, increasing the life expectancy and reliability of these devices.
