Nch 500 bis 650 V Super Junction Leistungs-MOSFETs
ROHM verwendet die Super-Junction-Technologie für 600 -800V Leistungs-MOSFETs. Mit dieser Technologie werden schnelle Schaltvorgänge und ein niedriger Durchlasswiderstand erreicht, wodurch die Anwendungsverluste reduziert werden. Rauscharme oder schnell schaltende Produkte sind ideal für PFC-Schaltungen in Stromversorgungsanwendungen in PCs, Servern, Ladegeräten und Beleuchtungen. Bei der Serie PrestoMOS™ handelt es sich um Produkte, die die schnellste Diode der Industrie mit ROHMs patentierter Technologie enthalten. Die Bauelemente sind auf Energieeinsparungen bei Motoren und Umrichtern spezialisiert. Die Serie PrestoMOS™ ist ideal für Motor- / Inverterschaltkreise, Totempol-PFC-Schaltkreise und LLC-Schaltkreise, die in Klimaanlagen, Kühlschränken, Waschmaschinen, Solarstromerzeugung usw. verwendet werden. 800 V-Produkte werden für LED-Beleuchtungen und industrielle Anwendungen empfohlen.

Fast Reverse Recovery Time type (PrestoMOS™ series)
What is PrestoMOS™?
PrestoMOS™ is a product in which the parasitic diode of the super junction MOSFET is sped up using proprietary patented technology.Due to its characteristic internal structure, the parasitic diode in a typical super junction MOSFET exhibits degraded recovery performance compared with a standard MOSFET. As a result, super junction MOSFETs could not be used in circuits that actively utilize the parasitic diode, such as inverters and bridge-type PFCs.
However, ROHM's PrestoMOS™ overcomes the drawback of super junction MOSFETs by speeding up the parasitic diode, contributing to significantly greater energy savings in applications utilizing bridge circuits and inverters for motor drive.
Replacement Example
Following the trend in recent years towards greater energy savings, ROHM has been contributing to increased application energy efficiency through outstanding recovery characteristics, prompting a growing number of designers to replace the combination of IGBT+FRD widely used in inverters with PrestoMOS™.
Applications
Motor drive, Energy-saving white goods, Charging stations,
Solar power conditioners, Various power supply circuits (LLC/Totem Pole PFC/Full-Bridge), etc.

Normal type (Low Noise/High-speed Switching)
Low Noise series
Low Noise series are low-noise products that place an emphasis on ease-of-use.
As a reaction to superior ON resistance and switching performance over conventional planar MOSFETs, super junction MOSFETs typically suffer from degraded noise characteristics. However, this series utilize an optimized internal gate construction that achieves lower noise, resulting in minimal noise-induced loss.
This makes them ideal for applications seeking to reduce noise, such as audio and lighting equipment.
In addition, they provide a level of noise performance equivalent to conventional planar types, making replacement easy.
High-speed Switching series
The High-speed Switching series are high-speed switching products that place an emphasis on high efficiency. Optimizing the internal MOSFET structure based on the low-noise series improves the gate charge characteristics (which is affected by switching speed).
This makes it possible to achieve higher efficiency via high-speed switching contributing to higher efficiency in PFC and LLC circuits.
Applications
Industrial equipment, Switching power supplies(Servers, Audio, TVs, Air Conditioners, Refrigerators, Washing Machines etc.), Loghting equipment, etc.
