Shanghai, China, June 10, 2025- Global renowned semiconductor manufacturer ROHM (headquartered in Kyoto, Japan) announced today the launch of a new SPICE model, ROHM Level 3 (L3), which improves convergence and simulation speed.

The loss of power semiconductors has a significant impact on the overall efficiency of the system, so the accuracy of the model is crucial in simulation verification during the design phase. The SiC MOSFET previously provided by ROHM uses the SPICE model "ROHM Level 1 (L1)", which improves the reproducibility of each characteristic and meets the requirements of high-precision simulation. On the other hand, this model has problems with simulation convergence and long computation time, which urgently need improvement.

The new model "ROHM Level 3 (L3)" can reduce simulation time by about 50% compared to previous L1 models while maintaining computational stability and switch waveform accuracy through the use of simplified model formulas. Thus, it is possible to perform transient analysis of the entire circuit with high precision and speed, which helps to improve the efficiency of device evaluation and loss confirmation in the application design phase.

The 4th generation SiC MOSFET model of ROHM Level 3 (L3) (37 models in total) has been released on the official website in April 2025, and users can download it through product pages and other channels. After the launch of the new model L3, previous models will continue to be provided. In addition, ROHM has also released a detailed user manual white paper to assist users in smoothly importing the new model.

Users can download the "Design Model" from the corresponding product page of the 4th generation SiC MOSFET
