Frd reverse recovery test
WebThe reverse recovery time (T rr) of the flywheel diode is critical. Choose a 600 V, 1 A ultrafast diode. The UF4005 is a low-cost ultrafast type, but the reverse recovery time is 75 ns. For greater efficiency, a faster diode like STTH1R06 (T rr = 25 ns) should be used. WebNotes: 6.

WebMar 20, 2024 · Re: Confusions about the Safe Operating Area (SOA) of Fast-Recovery-Diode (FRD) of IGBT Module. Dear Roi_XX , The 600kW is theoretical value for a 600A devise. We have improved the diodes until they reached the max performance of the rated current. In this case, 600A diodes are installed, so the allowable power is 600kW.
