Abstract

The first demonstration is reported of a high-voltage (9.2 kV) 4H-SiC bipolar junction transistor (BJT) based on a 50 μm, 7 × 10 14 cm-3 doped drift layer, achieving an emitter current density of 150 A/cm2 at VCEO = 5V, suggesting a specific on-resistance (RSP_ON) of 33 mΩ cm2 without considering current spreading or 49 mΩ cm2 if current spreading is considered. The result far exceeds the previous 4H-SJC BJT record of 3.2 kV with RSP_ON= 78 mΩ cm2.
