PrestoMOS™︎ Series – Optimal Energy Saving Solution for Motors・Inverters・LLC Converters

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.

The current Gen.3 PrestoMOSTm R60xxJNx Series has two main features.

Firstly, it has the best recovery characteristics (extremely small trr) in the market.

Secondly, it is able to control the self-turn-on function and ensures high short-circuit tolerance.

This series is very popular for motor driven white-goods such as air-conditioners and refrigerators, and EV charger stations.

In addition to the PrestoMOSTm, ROHM has two types of SuperJunction MOSFET,

one specializing in low noise characteristics and the other specializing in high speed switching.

The customer can choose between the two types according to their preference.
