FRED Pt® Gen 5 600 V Hyperfast Rectifiers

Vishay's FRED Pt Gen 5 600 V Hyperfast rectifiers come in a fully isolated TO-220 FullPAK 2L package. Offering the best reverse recovery performance for devices in their class, these 12 A and 15 A devices are designed to increase the efficiency of medium frequency converters and hard- and soft-switched or resonant designs. Compared to previous-generation solutions, these devices reduce reverse recovery charge (Q_rr) by 60% resulting in 90% lower recovery losses. Furthermore, the rectifiers deliver a 10% improvement in reverse recovery energy (E_REC) compared to the closest competing device, a softer recovery tail for improved EMI reduction, and more stable operation over their entire operating temperature range for increased thermal performance.

With this addition to its family of Gen 5 600 V FRED Pt rectifiers, Vishay is extending the benefits of high-end Si technology to different circuit topologies, including classic and bridgeless power factor correction (PFC) front-end configurations. The devices will serve as output and PFC rectifiers for AC/DC and DC/DC power stages in industrial applications, including air conditioners, off-board chargers, lighting, hybrid solar inverters, and UPS where they will guarantee system reliability and robustness without compromising performance. The devices are available in X-type, H-type, and W-type speed classes. For CCM and resonant applications with higher switching frequencies to 100 kHz and low di/dt to 350 kHz, W-type devices deliver lower Q_rr while X-type rectifiers offer lower forward voltage. RoHS-compliant and halogen-free, the rectifiers provide high-temperature operation to +175°C and an isolation voltage of 2,500 V.
