MOSFET Package Evolution and Trends

Semiconductor technology advancements drive the need for packaging technologies to keep pace. Increased loads in automotive motors, pumps, and industrial drives require larger die for higher current handling and thermal management. Conversely, reduced silicon geometries lead to smaller devices for wearables and highly integrated systems.

Diodes Incorporated offers a wide range of package options, from tiny DFN0604 (0.6mm x 0.4mm) to thermally-efficient PowerDI1012-8 (TOLL) and PowerDI1015 (top-side cooled) packages. Innovations in chip-scale packaging enable the lowest RDS(ON) for a given footprint. Diodes' PowerDI1012-8 (TOLL) package handles very high currents, and top-side cooled packages like PowerDI1015 improve thermal pathways. High-temperature (175°C) automotive SiC devices meet the demands of evolving EV systems. The DFN2020 (2mm x 2mm PCB footprint) offers the same current handling as SOT223 but uses 9% of the PCB area. Chip Scale Packages (CSP) facilitate the integration of protection MOSFETs for battery management.

The portfolio includes N- and P-channels, ranging from -600V to +1700V in single, dual, complementary, and H-Bridge (Quad) configurations. Technologies like shield-gate technology are used to reduce conduction and switching losses, ideal for BLDC motor driving. Lateral MOSFETs (LD-MOS) feature industry-leading Figure of Merit (FOM) for greater efficiency in DC-DC buck converters.
