With the increasing demands of Electric Vehicles, Industrial control, and communication, it is not only driven microcontrollers and power management ICs, but also Mosfet.
Metal-Oxide-Semiconductor Field-effect Transistor (MOSFET), a field effect transistor that can be widely used in analog circuits and digital circuits. There are kinds of product specifications of MOSFET. According to different technical characteristics, it can be divided into four categories: planar power MOSFET, medium and low voltage shielded gate MOSFET, trench power MOSFET, and high voltage super junction MOSFET.
Due to its high frequency, simple drive and good breakdown resistance, Mosfet has been widely used in power electronic circuits. The applications includes Automotive, Consumer Electronic, Industrial, and communications.
With the development of Vehicle electrification and intelligent in recent years, the demand for energy conversion continues to increase. It promote the rapid development of automotive-grade MOSFETs.
Infineon Mosfet for Automotive Application
Mosfet was early used in areas involving electric functions in fuel vehicles. With the start of vehicle electrification, the DC-DC medium and high voltage Mosfet, the super junction Mosfet in OBC, etc. are applied to the automotive power domain by means of electric braking to complete the conversion and transmission of electric energy. With the development of automobile intelligence, MOSFETs required for ADAS, security, infotainment and other functions are used as the basic devices for power conversion to support digital, analog and other chips to complete the function realization.
In addition to the interior of new energy vehicles, charging piles are also an area that requires a lot of Mosfet.
Charging piles can be divided into three categories: public DC, public AC and private. Among them, high-power DC piles can be charged the fastest, and a 150kW DC charger can add 200 kilometers of battery life to an electric vehicle in about 15 minutes.
In high-power DC charging piles, high-voltage superjunction MOSFETs have been widely used in power factor correction (Power Factor Correction, "PFC") of charging piles due to their lower conduction and switching losses, high reliability, and high power density. ”), DC-DC converters, and auxiliary power modules.
In the industrial field, most industrial equipment requires the use of Mosfet. The use of SiC MOSFETs in the industrial field can achieve high voltage resistance, high-speed switching and low on-resistance, and help reduce power consumption and system miniaturization. It is the development focus of all manufacturers at present. It has been widely used in photovoltaic energy storage, Rail transit, smart grid, UPS power supply, robotics and other fields.
Taking photovoltaics as an example, although photovoltaic power devices are still dominated by IGBTs, SiC MOSFETs have begun to be used in photovoltaic products above 30 kilowatts and 1,700 volt auxiliary power supplies. In addition, energy storage, industrial frequency conversion, etc. also require a large number of SiC MOSFET modules.
In the field of consumer electronics, power semiconductors are also widely used. Driven by 5G, the power consumption of electronic devices has increased, and how to improve charging efficiency has become a pain point for consumers. As a result, the "fast charging" and "flash charging" modes have emerged, and the requirements and demand for synchronous rectifier MOS transistors have continued to increase.
Manufacturers of Mosfet - Delivery Time and Price Trend
Judging from the current market size, driven by markets such as 5G and new energy vehicles, Mosfet will grow at a high rate of no less than 6.7%. The main manufacturers of Mosfet are Infineon, onsemi, STMicroelectronics, Renesas and so on.
With a market share of 24%, Infineon is the world's leading power semiconductor company and masters high-end power semiconductor technology. Its products mainly include Mosfet, IGBT, intelligent power devices and power integrated circuits.
onsemi has become the world's second largest power semiconductor company after acquiring Fairchild, with a market share of 12%. Its products include Mosfet, IGBT, new material devices, only power devices and power integrated circuits.
STMicroelectronics has a market share of 9%. Its power semiconductor products include Mosfet, IGBT, diode, power integrated circuit, etc.
Lead Time and Price Trend of Mosfet
From the data of the fourth quarter, most Mosfet delivery time is more than 40 weeks, and the delivery time and price trend are basically stable. The following is a comparison of the delivery period of the three major Mosfet manufacturers. It can be seen that the trend of the Mosfet delivery period remains stable. But the price trend of high and low-voltage Mosfet of onsemi is on the rise.
Mosfet is the most concerning type of electronic component besides MCU and PMIC. With the development of intelligence and automation, the demand for Mosfet will increase.
