OptiMOSTM 300 V increases the efficiency of hard switching applications and supports new designs

     Infineon Technologies AG launches OptiMOSTM 300 V, expanding its portfolio of medium voltage MOSFETs and setting a new standard in the power field effect tube market. The launch of the 300V OptiMOSTM helps Infineon further consolidate its market leadership in communication power supplies, uninterruptible power supplies (UPS), motor control, industrial power supplies, and DC/AC inverters.

     The newly launched OptiMOS 300 V helps increase power density, reduce system costs, and provide greater reliability. For the end user, this means saving energy costs. For example, in hard switching applications with AC/DC converters, OptiMOS 300 V can reduce power loss by 50%. This allows designers to increase the switching frequency, thus reducing the size of passive devices and even the entire system. In addition, OptiMOS 300 V provides a higher voltage spike margin, thereby improving the reliability, safety and ease of use of 60 V telecom rectifier designs. In addition, it reduces the number of stages required to cascade high-voltage switching power supplies. In addition, OptiMOS 300 V can also be applied to 110 V AC UPS.

     Richard Kuncic, Vice President and General Manager of the DC/DC Business at Infineon Technologies AG, said: "With the 300 V blocking capability, Infineon extends the industry-leading OptiMOS technology to today's non-mainstream voltage classes to support evolving applications such as multilevel converters. Due to the superior performance of OptiMOS technology and the wide range of applications, we hope that this voltage level will become the new standard in the power field effect transistor market."

     OptiMOS 300 V combined with fast diode technology, the reverse recovery charge Qrr is 70% lower than the market's last best comparable product. As a result of this feature, the body diode performs smoothly and minimizes voltage overshoot. OptiMOS 300 V in the TO-220 package delivers the industry's best on-resistance (RDS(on)) with a factor of excellence (FOM: RDS(on) x Qg) more than 58% lower than other available products. This can directly reduce on-off losses and improve the overall efficiency of high-current applications such as motor control.
