Select a Subcategory
Infineon's metal-oxide-semiconductor field-effect transistors (MOSFETs) are used for amplifying or switching electronic signals. In digital and analog circuits the MOSFET is undoubtedly the most common transistor. Reasons for this are the large packing density of the MOSFETs and the low production costs.

Infineon's RF MOSFETs
Infineon offers RF MOSFETs with several sub categories. The sub categories depend on the biasing resistor network at the RF input port. This could be fully integrated (full-biased), partly integrated (semi-biased) or not at all integrated (non-biased). RF MOSFETs can e.g. used in a main stream of a TV tuner, which is either a semi-biased or intelligent-switching concept. Single non-biased or single full-biased RF MOSFETs can for example be designed into a FM Radio tuner.
Key benefits of Infineon's RF MOSFETs
- Best-in-class noise figure and gain
- Excellent cross-modulation
- ESD robustness protected via on-chip gate protection diode
- 5th generation MOSFETs e.g. BF5030W, BG5120K fulfill the stringent technical requirement from the digital tuners, and as well support low power 3V designs
- Automotive quality (AEC Q101 qualified)
- RoHS compliant

Infineon’s low voltage OptiMOS™ portfolio offers high-end power MOSFETs in all voltage classes and packages allowing the designer to find the best combination of price and performance for his application. Short overload conditions confront the designer very often with huge thermal challenges. A deeper understanding of this topic results in a well-balanced combination of low-ohmic MOSFETs and improved thermal design.

The well known problems in a buck converter are overshoot and EMI issues. The overshoot problem, appearing during the high-side turn-on inbetween two MOSFETs, is adressed within the buck converter. Three possible solutions for solving the problems are shown: improve the layout of buck converter, use components with smaller stray inductance or by using MOSFTES technologies that helps to minimize the problems (like Infineon's packages CanPAK or SuperSO8) |
Infineon’s new CoolMOS™ C7 series is a revolutionary step forward in technology, providing the worlds’s lowest RDS(on) per package and, thanks to its low switching losses, efficiency improvements over the full load range. C7 is optimized for hard switching topologies such as Power Factor Correction (CCM PFC), Two Transistor Forward (TTF) and Solar Boost in applications such as Solar, Server, Telecom and UPS. The 650V breakdown voltage makes it suitable for both Solar and Switched Mode Power Supplies (SMPS) PFC stages where extra safety margin is required. |
