Vishay has introduced 10 rectifiers, which range from 15 to 75A. They are designed to increase the efficiency of AC/DC and DC/DC converters in electric and hybrid electric vehicles’ on-board chargers.
The company claims that the 15, 30, 60 and 75A Vishay Semiconductors rectifiers offer 30% lower reverse recovery losses than the closest competing rectifiers. The recovery losses are 48% lower than the company’s previous-generation FRED (Fast Recovery Epitaxial Diode) Pt devices, while maintaining low conduction and switching losses. The rectifiers also deliver improved light and full-load efficiency in high-speed LLC output rectification stages for on-board chargers in electric and hybrid electric vehicles.
Four of the rectifiers VS-E5TH1506THN3, VS-E5TX1506THN3, VS-E5TH3006THN3 and VS-E5TX3006THN3 are available in TO-220AC packages andsix, the VS-E5PH3006LHN3, VS-E5PX3006LHN3, VS-E5PH6006LHN3, VS-E5PX6006LHN3, VS-E5PH7506LHN3 and VS-E5PX7506LHN3, are supplied in TO-247AD packages and in X-type Hyperfast and H-type Ultrafast speed classes. The X-type devices have lower QRR, pbserves the company, while H-type rectifiers feature lower forward voltage. All rectifiers in the series are RoHS-compliant and halogen-free and offer high temperature operation up to 175°C.
Samples and production quantities are available now, with lead times of 12 weeks.
