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

Compared to previous-generation solutions, the Vishay Semiconductors devices released today reduce reverse recovery charge (Qrr) by 60 %, resulting in 90 % lower recovery losses. Furthermore, the rectifiers deliver a 10 % improvement in reverse recovery energy (Erec) 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 the latest 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 on performance.

The VS-E5TW1206FP-N3, VS-E5TX1206FP-N3, VS-E5TW1506FP-N3, and VS-E5TX1506FP-N3 are available in X-type and the new 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 Qrr, while X-type rectifiers offer lower forward voltage. RoHS-compliant and halogen-free, the rectifiers provide high temperature operation to +175 °C and isolation voltage of 2500 V.

Samples of the new FRED Pt rectifiers are available now. Production quantities are available with lead times of 20 weeks. More information please visit VS-E5TW1206FP-N3, VS-E5TX1206FP-N3, VS-E5TW1506FP-N3, and VS-E5TX1506FP-N3.
