Abstract：

The　robustness　of　SiC　MOSFET　body　diode　under　extreme　operating　condition　such　as　cryogenic　and　high　temperatures　becomes　a　crucial　factor　for　high　power/efficiency　applications.　In　this　paper,　the　dynamic　performance　of　1.2kV　SiC　MOSFET　body　diodes　is　systematically　investigated　from　90K　to　603K.　A　double　pulse　test　setup　capable　of　controlling　temperatures　from　90K　to　603K　is　used　to　measure　device　dynamic　performance　and　extract　parameters　including　recovery　time　(trr),　reverse　recovery　charge　(Qrr),　maximum　reverse　recovery　current　(Irm)　and　reverse　recovery　energy　loss　(Err).　The　effects　of　gate　resistance　and　load　current　on　device　dynamic　performance　are　also　examined.　©　2018　IEEE.
