X- and W-type Hyperfast rectifiers are in isolated package

Fred Pt Gen 5 600V Hyperfast rectifiers are available in isolated packages from Vishay Intertechnology. They are claimed to deliver best in class reverse recovery performance.

The rectifiers are offered in X-type and W-type speed classes. The 12 and 15A devices combine low Qrr down to 75nC. The four new Fred Pt Gen 5 600V Hyperfast rectifiers are available in a fully isolated TO-220 FullPAK 2L package. The 12A VS-E5TW1206FP-N3 and VS-E5TX1206FP-N3 and 15A 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, said Vishay. 

Compared to previous generation devices, the Vishay Semiconductors devices released today reduce reverse recovery charge (Qrr) by 60 per cent, resulting in 90 per cent lower recovery losses. The rectifiers deliver a 10 per cent 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 the entire operating temperature range for increased thermal performance. 

The Gen 5 600V Fred Pt rectifiers 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.

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 100kHz and low di/dt to 350kHz, 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 degrees C and isolation voltage of 2,500V. 

Samples of the new Fred Pt rectifiers are available now. Production quantities are available with lead times of 20 weeks. 

Vishay claims to manufacture one of the world’s largest portfolios of discrete semiconductors and passive electronic components for innovative designs in the automotive, industrial, computing, consumer, telecommunications, military, aerospace and medical markets.
