    BY399 3A 800V Soft Recovery Fast Switching Diode For Negative Switching Power Supplies

    BY399 3A 800V soft recovery fast switching silicon rectifier diode


    Description:


    Ultrafast rectifiers are designed in order to have very low forward voltage with an ultrafast reverse recovery. This makes ultrafast rectifier diodes very efficient for secondary output rectifications in high frequency switched mode power supplies. Ultrafast rectifiers can directly reduce switching loss and improve overall power efficiency due to a good combination between reverse recovery time and forward voltage. Some features and benefits include high reverse voltage surge capability, high thermal cycling performance, low thermal resistance and very low on-state loss. Also, the soft recovery characteristic of ultrafast rectifiers minimizes power consuming oscillations.


    Ultrafast Rectifiers are made for negative switching power supplies, as free wheeling diodes (such as in motor applications) and for use in inverters. They can also be found in military and other high reliability applications. Other regular applications include desktop personal computers, laptop and printer AC adaptors, DVD AC/DC power supplies, monitors, televisions and games units.
