SiC vs Si


SiC Schottky diodes enable fast switching with very low recovery charge compared to best-in-class Silicon devices.

SiC v SiC Competitors


UnitedSiC’s SiC Schottky diodes are best-in-class.

The low QRR reduces switch IRM losses.


Replace 8A Tandem Diode with 4A SiC

>5X Lower Qrr with 4A SiC Diode

SiC Qrr is Temperature Independent

4A SiC Diode VF(8A) ~ Si Tandem Diode VF(8A) at 125°C

Also available with Surge Bypass Option
