As a highly efficient PV module bypass diode, this latest SBR has a maximum package height of only 0.75 mm, enabling it to be integrated within the solar panel, 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 0.21 mm to total solar panel depth. In addition, the 9 mm long leads of the package support simple solder bar mounting, allowing solar panel manufacturers to avoid the use of expensive solder processes.

As an alternative to traditional axial lead diodes, the SBR12U45LH offers the industry’s lowest forward voltage drop for a rectifier at 0.38 V at 12 A and +125ºC, ensuring negligible heat generation and temperature rise during
operation. This results in safer and more reliable operation of solar panels.

Fully functional over the -65 to +200ºC temperature range, the rectifier meets long life warranty requirements and is compliant with the thermal test requirement of Solar Safety Standard IEC61730-2.
