600-V hyperfast rectifiers slash recovery losses - EDN

2022-10-08 09:14:06 By : Ms. Nancy Huang

Four new FRED Pt Gen 5 600-V hyperfast rectifiers from Vishay reduce reverse recovery charge by 60% compared to their predecessors, resulting in 90% lower recovery losses. The rectifiers also offer a 10% improvement in reverse recovery energy, a softer recovery tail for improved EMI reduction, and more stable operation over their entire operating temperature range for increased thermal performance.

The 12-A VS-E5TW1206FP-N3 and VS-E5TX1206FP-N3, along with the 15-A VS-E5TW1506FP-N3 and VS-E5TX1506FP-N3, increase the efficiency of medium-frequency converters and both hard- and soft-switched or resonant designs. Guaranteeing system reliability and robustness, the parts serve as output and power factor correction (PFC) rectifiers for AC/DC and DC/DC power stages in industrial applications, including off-board chargers, lighting, hybrid solar inverters, and uninterruptible power supplies.

Housed in fully isolated TO-220 FullPAK 2L packages, all four rectifiers are available in X-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 reverse recovery charge, 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 FRED Pt Gen 5 rectifiers are available now. Production quantities are available with lead times of 20 weeks.
