RURP56F85 5A, 6V Ultrafast Rectifier Features High Speed Switching ( t rr =52ns(Typ.) @ I F =5A ) Low Forward Voltage( V F =.5V(Max.) @ I F =5A ) Avalanche Energy Rated AECQ Qualified Applications Automotive DCDC converter Automotive On Board Charger Switching Power Supply Power Switching Circuits 5A, 6V Ultrafast Rectifier The RURP56F85 is an ultrafast diode with soft recovery characteristics(trr < 7ns). It has a low forward voltage drop and is of planar, silicon nitride assivated, ionimplanted, epitaxial construction. This device is intended for use as an energy steering / clamping diode and rectifier in a variety of switching power supplies and other power switching applications. Its low stored charge and ultrafast recovery with soft recovery characteristics minimizes ringing and electrical noise in many power switching circuits, thus reducing power loss in the switching transistor.
