Figure 3: ROHM's new, 4 th Generation SiC MOSFETs (source: TechInsights) When compared to the 3 rd Gen device, the 4 th Gen device has some similarities, and a number of striking differences. What remains similar is the approach adopted by ROHM to use a traditional trench MOSFET design, with channels on both of the gate-trench sidewalls.

$begingroup$ OP, this is the cause, but to avoid it for the future, just use the symbol for the NMOS, CTRL+RClick on it, change the Prefix from MN to X, and then change the name NMOS to the name of the subcircuit (here SCT2450KE, or whatever name there is).If you rely on auto-generated symbols, you'll end up with very ugly and confusing …

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.
