300 V High Efficiency MOSFETs

Infineon Technologies extends its medium voltage MOSFET portfolio with OptiMOS TM300 V, setting a new standard in the Power MOSFET market. In doing so, the company confirms its position as market leader enabling energy efficient solutions in applications such as telecom systems, uninterruptible power supplies (UPS), motor control, industrial power supplies and DC/AC inverters.

The new OptiMOS 300 V helps system designers to increase power density and reduce cost with the highest level of reliability. Ultimately, for the end user, this translates into energy cost savings. For example, in hard switching applications such as AC/DC converters OptiMOS 300 V cuts energy losses by 50 percent. This allows for higher switching frequencies and, consequently, passive component and solution size reduction. Furthermore, OptiMOS 300 V can provide voltage spike headroom for better reliability, safety and ease of design in a 60 V telecom rectifier. The number of stages required in cascaded high voltage switch mode power supplies can also be reduced. Additionally, 110 V AC UPS can now be realized with OptiMOS 300 V.

Incorporating fast diode technology, OptiMOS 300 V offers 70 percent lower reverse recovery charge Q rr compared to the next best alternative device. This characteristic leads to smooth body diode behavior and minimizes voltage overshoot. OptiMOS 300 V in the TO-220 package provides the industry's best R DS(on) with more than 58 percent lower Figure of Merit (FOM: R DS(on) x Q g) when compared to other available products. This translates directly into lower conduction losses and improved overall efficiency in high current applications such as motor control.

OptiMOS 300 V is available in two packages: D2PAK with RDS(ON) of 40.7 mW and TO-220 with RDS(ON) of 41 mW. Both packages are in production.
