Infineon's OptiMOS 3 40 V, 60 V, and 80 V products are intended for power conversion and power management applications that require high efficiency and power density. These applications include SMPSs, DC/DC converters, and DC motor drives in a wide range of products including computers, home appliances, small electric vehicles, industrial automation systems, telecommunications equipment, and consumer devices such as power tools, electric lawnmowers, and fans.
The OptiMOS 3 SuperSO8 products meet the needs of fast-switching SMPSs and DC/DC converters in a variety of applications. These include synchronous rectifiers in AC/DC SMPSs, primary-side switches, and secondary side-switches in isolated DC/DC converters and non-isolated (buck) industrial converters where space, power density, and maximum efficiency are key factors. With a thermal resistance of 1° K/W to the PCB, the possibility of top- and double-sided cooling and a continuous current rating of 100 A, the OptiMOS 3 MOSFET family sets a new standard for low-ohmic MOSFETs in the 40 V to 80 V classes. The family also includes the industry's first 60 V and 80 V breakdown voltage MOSFETs available in an S3O8 package. The S308 package represents a 60 percent footprint reduction over standard SO8 or SuperSO8 devices.
