IXYS Introduces New Generation Of Recovery Diodes In 600 To 1800V Range

IXYS Corp. announced the expansion of its new generation of ultrafast recovery diodes called the Sonic-FRD™ family. These new products are produced in IXYS’ own wafer fabrication plant, utilizing proprietary processing technology that is said to optimize the fast switching speed of the diode, with low forward voltage drop (Vf), and no "snappiness" for 600, 1200 and 1800V ratings.

The Sonic-FRD™ diode family is well suited for power applications with high switching frequencies (20-200 kHz), and especially in boost and free wheeling configurations, such as in power factor correction (PFC) circuits and switch mode power supplies (SMPS). All of these will benefit from the optimized characteristics of small reverse recovery current (Irr) and small stored charge (Qrr), as well as a soft recovery. The results are reduced energy losses for the diode as well as for the switching transistor in the power circuit. An added benefit of the soft recovery of these diodes in turn off is the minimized EMI noise they generate in switching and the elimination of the need to add costly snubber circuitry for the switching transistors.

The Sonic-FRD™ family have a Vrrm rating from 600 to 1800V with different current values from 5A up to 60A. More than 25 products in various configurations and packages include the isolated ISOPLUS-packages of IXYS. Some part types examples are: DHG5I600PA (5A, 600V); DHG30I600PA (30A, 600V); DHG10I1200PM (10A, 1200V); DHG40C1200HB (40A, 1200V); and DH60-18A, DH2x61-18A (60A, 1800V).
