This means Tesla need 3 Million SiC MOSFET dies every quarter to keep its production rate of Model 3, as of early January. Now, ST Microelectronics is producing 650V/100A Silicon Carbide MOSFET from it's fab in Catania, Italy. We took the hypothesis of a 4 mm x 4 mm die size. This matches a current density of 6.25 A/mm².

According to Delphi Technologies CEO Richard F. Dauch, the SiC-based inverter enables electrical systems of up to 800 V to significantly extend EV range and halve charging times compared with 400-V systems. "Doubling the voltage from 400 V brings a substantial range of benefits, both for the vehicle user and manufacturer," he said.

most Si MOSFET are typically driven with a VGS ≤ 10 V. For this reason, if were to replace a Si MOSFET by a SiC one, a modification of the driving voltage is recommended. Although 10 V is above the typical threshold voltage of a SiC MOSFET, the conduction losses at such a low VGS would most likely lead to a thermal runaway of the device.

Ein SiC-MOSFET ist rückwärtsleitend (vergleiche Abschnitt 4), das heißt, bei entsprechendem Betrieb entfallen die Schaltverluste der Diode. Im Gegenzug erhöhen sich allerdings die Durchlassverluste, weil die Abkommutierung der Motorwicklung jetzt nicht mehr über die Freilaufdiode erfolgt, sondern durch den eingeschalteten SiC-MOSFET.

The results are highest efficiency, higher switching frequencies, less heat dissipation, and space savings – benefits that, in turn, also reduce the overall system cost. We identified this potential almost 30 years ago and established a team of experts in 1992 to develop SiC diodes and transistors for high-power industrial applications.
