Diodes Incorporated SBR® Super Barrier Rectifiers

Diodes Inc SBR® Super Barrier Rectifiers use a MOS manufacturing process to create a superior two-terminal device with a lower forward voltage than comparable Schottky diodes while possessing the thermal stability and high reliability characteristics of PN epitaxial diodes. SBR Diodes are designed for high power, low loss and fast switching applications. The presence of a MOS channel within its structure forms a low potential barrier for the majority carriers. That means SBR forward bias operation at low voltage is similar to a Schottky diode. The leakage current is lower than Schottky Diode in reverse bias due to the overlap of the P-N depletion layers and the absence of potential barrier reduction due to the image charge.

Features

  • Very low on-state losses (Vf), even for high-voltage devices, and operation at elevated currents
  • Low leakage currents, even for higher current devices, and operation at elevated temperatures
  • Dynamic device operation to permit the use of a single component for wide-band operation
  • Increased ruggedness of the device by utilizing precision state-of-the-art IC manufacturing processes
  • Superior surge resistance due to the absence of Schottky junctions
  • Versatile design to allow entire product range to benefit from technology and permit high voltage devices to achieve ultra-low Vf parameter
  • Repetitive avalanche capability to compensate for inadequacies in fragile Schottky reverse behavior, thus providing highest reliability factor

Applications

  • Switch Mode Power Supplies (SMPS)
  • Buck/boost diodes for DC-DC conversion
  • Battery chargers
  • Reverse polarity protection
  • Solar panels
  • LED Lighting
  • Automotive applications
