Ideal diodes

Reduce wasted power consumption by 10 times using ideal diodes

Ideal diodes are integrated circuits consisting of a gate regulation amplifier, power MOSFET, protection circuitry, control logic and diagnostic functions. They are designed to mimic the conducting and blocking functionality of Schottky diodes while providing significant reductions in forward voltage drop, internal power dissipation and reverse DC leakage current.

Schottky diodes are commonly used to power “OR” primary and backup power supplies in mission critical applications; as well as provide reverse polarity protection to sensitive downstream components in the event of a miswired power supply or incorrectly inserted battery. When replaced with ideal diodes, power losses can be decreased by over 90%.

Key features & benefits

  • Low power loss upgrade for Schottky diodes in power OR-ing applications 
  • Automatic transition between OR-ed supplies ensure continuity of power to load 
  • Forward voltage drop 10 times smaller increases voltage margin to downstream loads 
  • Reverse biased DC leakage current up to 100 times lower
  • Reverse voltage protection protects sensitive loads from destructive polarity inversions  
  • Specified from -40 °C to +125 °C 

Key applications

  • Building automation 
  • Smart meters 
  • OR-ed primary and battery backup 
  • Automotive telematics units 
  • Reverse battery protection of IoT and consumer products
