Wolfspeed added four new SiC Schottky diodes to its portfolio in response to continuous demand for components with larger nominal current ratings. The new 650 and 1200 V Z-Rec SiC Schottky diodes include zero reverse recovery current, zero forward recovery voltage, high frequency operation with low EMI, temperature-independent switching behavior, fast switching, reduced heat sink requirements, near-zero switching losses, and higher efficiency compared to analogous silicon diodes. A positive temperature coefficient on VF also enables parallel devices without thermal runaway, and each of the four new diodes provides engineers with an attractive price/performance ratio when compared to competitive offerings.
The new 650 V 12 A C3D12065A and 16 A C3D16065A Z-Rec SiC Schottky diodes are supplied in TO-220-2 packages, and are targeted at PFC boost stages in server power supplies, especially next-generation systems rated for 1,100 W, 1,600 W, 2,000 W, and 2,400 W with low-line or high-line inputs. They’re also available as bare die with part numbers: CPW2-06500S012B and CPW2-0650-S016B. The new 650 V 2 x 15 A C3D30065D Z-Rec diodes are supplied in TO-247-3 packages, and are best suited for rectification applications in 3 – 5 kW power supplies. Also supplied in TO-247-3 packages, the new 1,200 V 2 x 7.5 A C4D15120D Z-Rec diodes are ideal for use in PV inverters and on- and off-board chargers.
Additionally, all four new diodes have a dV/dt rating of 200 V/ns. All four of the new Z-Rec SiC Schottky diodes are also halogen-free, RoHS compliant, and REACH certified. Wolfspeed: http://www.wolfspeed.com/power/products/sic-schottky-diodes/table
