Vishay Intertechnology, Inc has released four new FRED Pt Gen 5 600V Hyperfast rectifiers in a fully isolated TO-220 FullPAK 2L package. Providing the best reverse recovery performance for devices in their class, the 12A VS-E5TW1206FP-N3 and VS-E5TX1206FP-N3 and 15A VS-E5TW1506FP-N3 and VS-E5TX1506FP-N3 are intended to improve the efficiency of medium frequency converters and hard- and soft-switched or resonant designs.

Compared to previous-generation solutions, the devices lower reverse recovery charge (Qrr) by 60%, providing 90% lower recovery losses. Furthermore, the rectifiers deliver a 10% improvement in reverse recovery energy (Erec) compared to the nearest competing device, a softer recovery tail for enhanced EMI reduction, and more stable operation over their full operating temperature range for increased thermal performance.

With the most recent addition to its family of rectifiers, the company is extending the benefits of high-end Si technology to various circuit topologies, including classic and bridgeless 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 ensure system reliability and robustness with no compromising on performance.

The devices are offered in X-type and the new W-type speed classes. For CCM and resonant applications with higher switching frequencies to 100kHz and low di/dt to 350kHz, W-type devices deliver lower Qrr, while X-type rectifiers provide lower forward voltage. RoHS-compliant and halogen-free, the rectifiers provide high-temperature operation to +175C and an isolation voltage of 2500V.
