SuperJunction MOSFETs

ROHM utilizes super junction technology for its high voltage (600V+) power MOSFETs.
The result is high-speed switching and low ON resistance, making it possible to reduce application loss. ROHM offers two types, one featuring low noise specifications and the other delivering high-speed switching, allowing customers to select the ideal solution based on application requirements. In addition, the PrestoMOSTM series achieves greater energy savings in motors and inverters - a drawback of super junction MOSFETs - by incorporating the industry’s fastest diode utilizing ROHM’s patented technology.

3 Advantages of ROHM Super Junction MOSFETs

  • ① Expanded lineup includes 3 series tailored to customer needs
  • ② Each series offered in a range of packages and ON resistances
  • ③ High quality and performance provided, along with a comprehensive support system

What is PrestoMOSTM?

PrestoMOSTM 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 PrestoMOSTM 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.

What is PrestoMOS™?

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™.

Achieve greater energy savings by replacing with ROHM's PrestoMOS™

Feature ① Industry-leading recovery characteristics

ROHM’s PrestoMOSTM series utilizes original patented technology to accelerate the parasitic diode, achieving the industry’s fastest reverse recovery time (trr) - a key characteristic. However, faster diode speeds typically generates steep changes in the current, which tends to increase oscillation.
For our 3rd Generation PrestoMOSTM (R60xxJNx Series), structural optimization makes oscillation difficult during recovery. This facilitates the design and implementation of countermeasures by the customer against oscillation, making them ideal for applications experiencing oscillation during recovery.

Feature ① Industry-leading recovery characteristics

Feature ② Pursuing greater ease-of-use

ROHM’s PrestoMOSTM series is designed for bridge-type circuits and motor inverters requiring high short-circuit breakdown tolerance and self turn-ON prevention. Low short-circuit breakdown tolerance increases the possibility of MOSFET breakdown, while the occurrence of self turn ON can lead to significant power loss.
The R60xxJNx series of 3rd Generation PrestoMOSTM feature an optimized internal structure that makes it possible to clear both of these issues.
Compared to the latest competitor products, class-leading short-circuit breakdown tolerance is achieved, providing a greater level of safety. In addition, self turn ON prevention is ensured, minimizing operating power loss.

Feature ② Pursuing greater ease-of-use

ROHM Super Junction MOSFETs (2 Types)

ROHM offers 2 types of super junction MOSFETs, a low noise type (R6xxxENx series) and a high-speed switching model (R6xxxKNx series), available in various package types in both 600V and 650V withstand voltages.
The R6xxxENx series places an emphasis on ease-of-use, and achieves superior performance in noise-sensitive applications.
The R6xxxKNx series is focused on high efficiency and delivers excellent performance in applications demanding high-speed switching.
Both the R6xxxENx and R6xxxKNx series are offered in the same ON resistances, making it possible to select the ideal model based on set needs.
An 800V product is also available for high-speed switching specifications, achieving the industry's highest level of performance.

Low Noise Specifications: R60xxENx/R65xxENx Series

The R6xxxENx 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, the R6xxxENx 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.
