650V SiC Schottkys from 4A to 12A

Diodes has introduced some 650V SiC Schottky diodes, rated at 4, 6, 8, 10 or 12A.

Called the DSCxxA065LP series, they come in a 8 x 8 x 1mm T-DFN8080-4 package.

The company claims a leading Qc x Vf figure-of-merit, but does not include the numbers in its data sheets, so Electronics Weekly unleashed its calculator to find typical 25°C values of 7.1, 10.8, 16, 18.9 and 15.4VnC respectively at their rated current, 400V and 200A/μs.


Reverse leakage is 20µA max at 25°C.


Taking the 12A DSC12A065LP as an example, this rises to 190µA at 175°C. Typical figures are 190nA for 25°C and 2.6µA at 175°C.

Regarding the low-profile T-DFN8080-4 package, Diodes said: The surface-mount package requires less board space and provides a larger heat pad [than the] TO252 DPAK.”

Applications include dc-dc and ac-dc conversion in renewable energy, data centres and industrial motor drives.
