With the rapid growth of the global electric vehicle market, improving the energy efficiency of electric vehicles has become one of the key goals of the industry. Renesas, a leader in semiconductor technology, today announced the launch of its 100V high-power N-channel MOSFET, the RBA300N10EANS and RBA300N10EHPF, based on a new MOSFET wafer fabrication process, REXFET-1. The release of this innovative product marks an important breakthrough in Renesas' power semiconductor field and provides strong technical support for the energy efficiency improvement of electric vehicles.
Technological innovation: performance improvement and process breakthrough
Renesas' REXFET-1 process has been significantly optimized in terms of on-resistance, gate-leakage charge, and package size, significantly improving the overall performance of the new MOSFETs.
First of all, the on-resistance of the new product has been reduced by about 30%, and this optimization has a direct impact on the reduction of power losses. For example, in the motor control system of an electric vehicle, the reduction of on-resistance can effectively reduce energy waste, thereby improving system efficiency. Studies have shown that the reduction in on-resistance can help improve the overall energy efficiency of electric vehicles by about 30%. This improvement is critical to increasing range and reducing operating costs.
In addition, improvements in the REXFET-1 process are reflected in the reduction of gate leakage charge (Qg), which is reduced by 10% for the new MOSFETs and 40% for Qgd (the amount of charge that needs to be injected into the gate during the Miller plateau stage). These changes significantly improve the switching speed and response time of MOSFETs, especially in high-frequency switching applications. For example, in the inverter of electric vehicles, the fast switching of MOSFETs can reduce switching losses and improve power conversion efficiency.
In terms of packaging, Renesas uses industry-standard TOLL and TOLG packaging technologies to reduce the package size by 50% compared to conventional TO-263 packages. This compact package design not only saves PCB space, but also increases the integration and flexibility of the system. For example, in the battery management system of an electric vehicle, a smaller package can help enable a more compact battery control module design, improving the overall performance and reliability of the system.

Market application: far-reaching impact in the field of electric vehicles
Renesas' new MOSFETs have a wide range of applications in the electric vehicle industry, covering a wide range of key areas such as motor control, battery management, power management, and charging management.
In terms of motor control, the new MOSFETs have the advantages of low on-resistance and fast switching, which can improve the efficiency and response speed of electric vehicle motors. This is especially important for high-power demand scenarios such as acceleration and climbing. The electric vehicle motor control system using Renesas' new MOSFETs provides a longer range and more powerful power output with the same battery capacity.
In terms of battery management systems, Renesas' new MOSFETs are optimized for use in the charging and discharging process due to their high current switching capabilities and low power consumption. Specifically, the new MOSFETs can be used in the charge/discharge control circuits of the battery pack to ensure the safety and stability of the battery during charging and discharging. Its low-loss nature also reduces energy waste and improves the efficiency of battery management.
In addition, Renesas' new MOSFETs can effectively improve charging efficiency in on-board chargers and DC/DC converters for electric vehicles. With more efficient power conversion, charging times are shortened and energy losses are significantly reduced. For example, on-board chargers with Renesas' new MOSFETs enable battery charging in a shorter period of time, improving the overall efficiency of the charging system.
