The n-channel SiE876DF is targeted at industrial-type power supplies, motor control circuits, AC/DC power supplies for servers and routers, and systems using point-of-load (POL) power conversion. It will also be used as a primary side switch or for secondary side rectification in higher voltage intermediate bus conversion (IBC) designs.
In each of these applications, the low on-resistance of the SiE876DF will translate into lower conduction losses and thus save on energy. In addition to the low conduction losses provided by its TrenchFET® silicon, the double-sided cooling provided by the PolarPAK package enables better thermal performance for high-current applications. This allows for operation with a lower junction temperature. The PolarPAK’s leadframe-based, encapsulated design also offers increased protection and reliability, in addition to simplifying manufacturing, since the die is not exposed. The device offers the same layout as other PolarPAK devices with a drain-source voltage rating under 150 V, thus simplifying PCB design. The SiE876DF is also 100 % Rg- and UIS-tested.
