What is an Ultrafast Rectifier?
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.
Types of Ultrafast Rectifiers
There are many different kinds of ultrafast rectifiers and at Future Electronics we stock many of the most common types categorized by maximum average rectified current, maximum reverse voltage, maximum reverse recovery time, forward voltage, packaging type and maximum reverse current. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common sizes for maximum average rectified current are 1 A, 2 A, 3 A, 8 A and 30 A. We also carry ultrafast rectifiers with maximum average rectified current as high as 365 A. Forward voltage can range from 550 mV to 2.7 kV, with the most common ultrafast rectifier semiconductor chips having a forward voltage of 1.1 V, 1.25 V or 1.3 V.
