OptiMOS™ Power MOSFETs provide excellent best-in-class performance. Features include ultra low RDS(on) as well as low charge for high switching frequency applications. StrongIRFET™ Power MOSFETs  are  designed for rugged industrial applications and are ideal for designs with a low switching frequency as well as those that require a high current carrying capability.

These graphs show the recommended technology for best fit standard components, price performance and differentiated products according to switching frequency.

For low frequency applications, OptiMOS™ 5 is the best fit when Best-in-Class performance is required. However, StrongIRFET™ is recommended for 20 V to 75 V applications when best-in-class performance is not essential and cost is a more significant consideration.

For best-in-class performance at voltages from 80 V to 150 V, OptiMOS™ 5 is recommended. If best-in-class is not essential and price/performance is more important, then OptiMOS™ 3 is the recommendation.

Voltages above 150 V are available in OptiMOS™ 3. In addition, older Trench MOSFETs, shown here as HEXFET™, are an option for highly commoditized markets where cost is the main consideration.

For high frequency applications, OptiMOS™ 5 is recommended for best-in-class and price/performance up to 150 V. OptiMOS™ 3 can be considered where high performance is less essential. As with low frequency applications, OptiMOS™ 3 is available for voltages above 150 V.

Low Frequency Applications < 100 kHz

High Frequency Applications < 100 kHz

Infineon’s OptiMOS™ portfolio, now complemented by StrongIRFET™ Power MOSFETs, creates a truly powerful combination. The joint portfolio, covering 20 V up to 300 V MOSFETs, can address a broad range of needs from low to high switching frequencies. The tables below provide a guidance overview for the recommended OptiMOS™ or StrongIRFET™ products for each major sub-application and voltage class.

The combined portfolio covers a broad range of packages. Shown here are the packages available by voltage class range. Please note, not all packages are available in each voltage class. For new products, there will be a consolidation of package names. CanPAK™, S308 and PQFN 5×6 will be named DirectFET™, PQFN 3.3×3.3 and SuperSO8 respectively in the future.
