The 4th Gen Fast Recovery Diodes Ideal for Industrial and Consumer Equipment
ROHM will continue to expand the package lineup of the RFL/RFS series to provide automotive support while expanding applicability by reducing power consumption.
The 4th Generation 650V fast recovery diodes (FRDs), the RFL/RFS series from ROHM feature low forward voltage (VF), fast reverse recovery time (trr) respectively, as well as ultra-low noise characteristics. The new devices are ideal for industrial and consumer equipment that handle large amounts of power, such as air conditioners and EV charging stations.
Optimizing the device structure and materials allows the RFL/RFS series to achieve the optimum balance of VF and trr, which are important characteristics for FRDs but are in a trade-off relationship.
The low VF RFL series reduces VF by approx. 3.2% and trr by about 8.3% over the conventional RFN series, while the high-speed RFS series decreases VF by approx. 17.9% vs the conventional RFUH series. Both products contribute to higher power supply efficiency through optimal design based on circuit requirements. Furthermore, ultra-low noise diode recovery characteristics are achieved, they help to reduce both workload and components for noise.
Going forward, ROHM will continue to expand the package lineup of the RFL/RFS series to provide automotive support while expanding applicability by reducing power consumption.
