Infineon and Rohm introduce new Schottky diodes to power electric vehicles

Nowadays, the global automobile industry is developing in the direction of electrification, and the technological innovation of electric vehicles keeps pushing the market forward. Power semiconductors are key components in electric vehicles, especially Schottky diodes, in order to meet the market demand for high efficiency and high reliability, Infineon Technologies AG and ROM Semiconductor jointly launched a new generation of Schottky diodes, specifically designed for electric vehicles and hybrid vehicles, in order to improve energy efficiency and reduce energy loss.

The core technology of the new Schottky diode

The new diode from Infineon and Rohm combines the latest in semiconductor material science and manufacturing processes to improve performance through a very creative design. These diodes use advanced gallium nitride and silicon material technology, and have a much lower forward voltage drop than traditional Schottky diodes. In this way, the power conversion efficiency of electric vehicles is greatly improved, and the service life of the battery can be extended a lot.
The reverse recovery characteristic of the new diode is also improved particularly well. Traditional Schottky diodes in high frequency applications, there may be reverse recovery problems, the new generation of diodes with a higher reverse breakdown voltage, can effectively reduce this problem, to provide more smooth power conversion for electric vehicles. In addition, its thermal stability is also optimized, even in a high temperature environment, it can work steadily, ensuring that the performance of electric vehicles will not regress under various difficult conditions.

Design flexibility and application scenarios

In the application of electric vehicles, the design of power electronic systems is very complex and changeable. The new Schottky diodes from Infineon and Rohm not only increase system efficiency, but also provide designers with more flexibility. These diodes can be used not only in chargers and inverters, but also in electric vehicle powertrains, energy management systems, and various auxiliary systems.

In high frequency switching applications, the dynamic characteristics of the new Schottky diode are quite good, supporting frequencies up to 200kHz. This allows electric vehicles to be more efficient during battery charging and energy recovery, with better energy flow and less heat loss. Whether driving in the city or on the highway, the electric car's powertrain can maintain a particularly good performance.

Reliability and long life characteristics

The reliability of electric vehicles is very important, especially when the driving conditions are always changing. To this end, the new Schottky diodes from Infineon and Romm are manufactured to stricter standards, ensuring that each product can stand the test of actual use. These diodes not only passed the strict temperature cycle test and wet heat test, but also ensured the stability under high load conditions in terms of material selection and structural design.

At the same time, considering the operating environment of electric vehicles, the performance of the new Schottky diode against electromagnetic interference is quite good. Electric vehicles at high speed and power battery fast charging and discharging, may produce a lot of electromagnetic interference, this diode through optimized layout design and high insulation materials, the interference to other circuits to effectively reduce, the overall stability and safety of the system to improve.

Environmental performance

Now that the world is emphasizing sustainable development, the production and operation of electric vehicles must also consider environmental factors. The new Schottky diodes from Infineon and Rohm are produced in strict accordance with environmental standards and have a reduced environmental impact. The materials used in these diodes are strictly selected to ensure that they will not emit harmful things when used, in line with international environmental regulations.
Moreover, the characteristics of efficient energy conversion and low energy loss not only make the driving range of electric vehicles longer, but also help reduce the carbon footprint, which is too in line with the green development trend of future transportation.
Market prospect

The electric vehicle market is expanding particularly fast and is expected to explode in the next few years. In the face of such fierce market competition, enterprises must constantly innovate in order to meet the increasing needs of consumers. The new Schottky diode from Infineon and Rohm is an important product to meet this change in the market. With its outstanding performance, reliability and flexibility, it can provide electric vehicle manufacturers and designers with efficient solutions to help them seize the opportunity in the future market.

Infineon and Rohm have been working in the semiconductor field for many years, and they will continue to strive for technological innovation to promote the rapid development of electric vehicles and provide users around the world with more efficient and environmentally friendly mobility options. Whether in electric vehicle powertrains, charging facilities, or ordinary power management, the application of the new Schottky diode will certainly open up a more efficient and reliable era of intelligent transportation.
