Courtesy: STMicroelectronicsSTMicroelectronics' Field-Effect Rectifier diodes (FERD) offers a unique trade-off between low forward voltage drop (VF) and low leakage current (IR) that allows designers of equipment such as battery chargers and notebook adaptors to meet the most stringent energy-efficiency standard requirements without the expense of using synchronous rectification techniques.

With its lower forward voltage drop and better managed leakage current, the ST technology increases the current that can flow for a given package power-dissipation capability. Benefits include faster charging of smart phones and tablets, reduced notebook-charger size and weight, and increased lifetime of the equipment as the FERD diodes operate at lower temperature.

The FERD technology is useful for applications and systems like freewheeling or reverse battery protection in automotive applications; OR-ing in telecom power supplies; or rectification in industrial systems.
