Ultra fast recovery rectifier diode UF5408 5.0A 1000V, package DO-27
Description:
A diode is a one-way valve for electricity. Diodes allow flow of electricity in one direction. Most diodes have a painted line on one end showing the direction or flow. The negative side is normally white.
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.
Features:
• Diffused junction
• Fast switching for high efficiency
• High current capability and low Forward Voltage Drop
• Surge overload rating to 150A peak
• Low reverse leakage current
• Plastic material has UL flammability classification 94V-0
Application:
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.
