Super Junction MOSFET PrestoMOS™ (High-speed Trr) Series

ROHM’s PrestoMOS™ series of power MOSFETs features the industry's fastest reverse recovery characteristics to achieve lower power consumption. Leveraging proprietary lifetime control technology results in ultra-fast trr. The result is approx. 58% less power loss at light loads compared with IGBTs. In addition, raising the reference voltage needed to turn ON the MOSFET prevents self turn-ON, which is one of the main causes of loss. And optimizing the characteristics of the built-in diode allowed ROHM to improve the soft recovery index specific to super junction MOSFETs in order to reduce noise which can lead to malfunctions. Eliminating these barriers to circuit optimization provides customers with greater design flexibility.
