Low profile rectifier simplifies solar panel design

Diodes has unveiled a 12A rated super barrier rectifier, which it says addresses key design and manufacturing concerns of solar panel makers producing next generation PV modules.

The SBR12U45LH has a maximum package height of 0.75mm, enabling it to be integrated within the solar panel and effectively removing the need for separate junction boxes. With package side located leads, the PowerDI-5SP can be mounted into recesses in the back layers, adding only 0.21mm to total solar panel depth. In addition, the 9mm long leads of the package support simple solder bar mounting, helping solar panel manufacturers avoid the use of expensive solder processes. The SBR12U45LH is said to offer the industry's lowest forward voltage drop for a rectifier at 0.38V at 12A and 125ºC, ensuring negligible heat generation and temperature rise during operation, resulting in safer and more reliable operation of solar panels. Fully functional over the temperature range of -65 to 200ºC, the rectifier meets long life warranty requirements and is compliant with the thermal test requirement of Solar Safety Standard IEC61730-2.
