New 4th Gen 650V Fast Recovery Diodes
4th Generation FRD, the RFL/RFS series, featuring low VF, fast trr respectively, as well as ultra-low noise characteristics. The devices are ideal for industrial and consumer equipment that handle large amounts of power, such as 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.
Features
- Low VF Type: RFL series
- High Speed trr Type: RFS series
