Vishay Intertechnology Releases New 15 A and 25 A Single-Phase Single In-Line Bridge Rectifiers With Low Forward Voltage Drop Down to 0.73 V for Improved Power Efficiency

The LVB1560 offers a current rating of 15 A and low forward voltage drop down to 0.73 V at 7.5 A, while the LVB2560 features a current rating of 25 A and forward voltage down to 0.76 V at 12.5 A. The devices’ low VF reduces power loss for increased power efficiency and energy savings.

The bridge rectifiers released today feature maximum peak reverse voltage ratings of 600 V. Offering an oxide planar chip structure, the devices provide high case dielectric strength of 2,500 VRMS.

The LVB1560 and LVB2560 are the ideal choice for primary side ac-to-dc full-wave rectification in switchmode power supplies for high-efficiency desktop PCs, servers, telecommunication systems, home appliances, and white goods applications.

The rectifiers’ + 275 oC, 10 second solder dipping process per JESD 22-B106 enables high reliability in wave soldering or manual soldering. The devices are compliant to RoHS Directive 2002/95/EC and WEEE 2002/96/EC, and are halogen-free according to the IEC 61249-2-21 definition.
