lakshmisudhakar_k Posted February 21, 2010 Report Share Posted February 21, 2010 Hi gentlemen , any one can give some stuff regarding measuring of reverse recovery currentModerator Edit: Fixed block capacitals.

Hero999 Posted February 21, 2010 Report Share Posted February 21, 2010 What do you mean?The reverse current is a tiny leakage current that flows when the reverse voltage is applied. It's normally insignificant for silicon diodes but for som Schottky diodes it's significant. It can be measured by using a voltage source set near the diode's absolute maximum rating an ammeter which is capable of measuring the current listed on the data sheet.The reverse recovery time, is how long it takes for the diode to turn off when the voltage is reversed or on when the voltage is applied in the forward direction. It can be measured using a 'scope and a square wave generator with a push-pull output. Quote Link to comment Share on other sites More sharing options...
indulis Posted February 21, 2010 Report Share Posted February 21, 2010 Reverse current and reverse recovery current are not the same thing. Ultra-fast and fast recovery diodes have a much longer Trr time (hence a higher reverse recovery current) when compared to Schottky Quote Link to comment Share on other sites More sharing options...
