SemiSouth doubles current rating of 1200V SiC diodes to 10A

SemiSouth Laboratories Inc of Starkville, MS, USA, which designs and manufactures silicon carbide (SiC) devices for high-power, high-efficiency, harsh-environment power management and conversion applications, has doubled the current rating of its DPAK-packaged 1200V SiC diodes from 5A (for the SDB05S120 in a TO-252 package, launched last October) to 10A (for the new SDB10S120 in a TO-252-2L package).

The 1200V/10A SDB10S120 features a positive temperature coefficient for ease of paralleling, and temperature-independent switching behavior. The maximum operating temperature is 1750C. The devices also exhibit zero forward and reverse recovery current. Total capacitive charge is 40nC. The true two-lead DPAK (TO-252-2L) package has a mounted footprint (nominal) of 9.8mm x 6.6mm and measures just 2.29mm high.

“By again extending our leadership position in silicon carbide with these new 1200V/10A diodes we are enabling manufacturers of products such as solar inverters, SMPS [switched-mode power supplies], induction heaters, UPS [uninterruptible power supplies] and motor drives – and well as anyone building PFC circuits – to benefit from increased performance and reduced space,” says senior VP of sales & marketing Dieter Liesabeths.

Samples are available now, with volume production starting in June. Devices are priced at $8.66 in 1000-unit quantities.
