Wolfspeed has extended its SiC Schottky diodes portfolio with four new products. The characteristics of the new 650V and 1200V Cree 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 significantly higher efficiency as compared to analogous silicon diodes. A positive temperature coefficient on VF also enables parallel devices without thermal runaway.

The new 650V 12A C3D12065A and 16A 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 1100W, 1600W, 2000W, and 2400W 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 650V 2x15A C3D30065D Z-Rec diodes are supplied in TO-247-3 packages, and are best suited for rectification applications in 3–5kW power supplies. Also supplied in TO-247-3 packages, the new 1200V 2×7.5A C4D15120D Z-Rec diodes are interesting for use in PV inverters and on- and off-board chargers.
