Performance and design possibilities in hard switching applications



The new OptiMOS™ 300V MOSFETs from Infineon, incorporating fast diode technology, are especially optimized for body diode hard commutation. Infineon again sets a benchmark with this additional voltage class, extending the OptiMOS™ product portfolio from 20V up to 300V.


OptiMOS™ 300V devices with excellent hard commutation ruggedness, not only demonstrate impressive on-state resistance (R DS(on)) and Figure of Merit (FOM), but also provide high system reliability through the lowest reverse recovery charge (Q rr) available on the market. With the new 300V OptiMOS™ series, Infineon brings a new level of performance in hard switching applications such as telecom, uninterruptible power supplies (UPS), industrial power supplies, DC-AC inverters and motor control.


The 40.7mΩ OptiMOS™ 300V in D 2PAK reduces conduction loss and improves overallefficiency in high current applications such as motor control. The industry’s lowest FOM, more than 30% less than alternative devices, cuts system power losses. This also enables fast switching in switched mode applications such as synchronous rectification in 60V telecom systems.
