What are the measures for surge suppression? The reasons for generating surges are multifaceted, and surges are a type of spike pulse with high rising speed and short duration. Overvoltage in the power grid, switch ignition, reverse voltage, static electricity, and motor/power supply noise are all factors that cause surges. And surge protectors provide a simple, economical, and reliable protection method for power surge protection of electronic devices.

Instructions for using silicon carbide (SiC) diodes When using silicon carbide (SiC) diodes, some safety factors should be taken into account, such as avoiding excessive current flowing through the diode to prevent damage. During use, attention should also be paid to circuit design and diode selection to ensure optimal system performance.

Prospect sharing of silicon carbide (SiC) substrate sheets Silicon carbide (SiC) substrate is one of the key materials for manufacturing SiC devices, which can provide high lattice matching, low defect density, and high-quality surface flatness. With the continuous expansion of the silicon carbide power device market, silicon carbide substrate sheets have also been widely used and are expected to continue to maintain rapid growth in the coming years.

Analysis of Silicon Carbide (SiC) Technology Barriers: What are the Silicon Carbide Technology Barriers Groove type silicon carbide power devices have greater manufacturing difficulty. According to the different device structures, silicon carbide power devices can be mainly divided into planar devices and trench devices. Flat silicon carbide power devices have good unit consistency, simple manufacturing process, but are prone to JFET effect and have high parasitic capacitance and on state resistance. Compared to planar devices, groove type silicon carbide power devices have lower unit consistency and more complex manufacturing processes. However, the groove structure is beneficial for increasing device unit density, reducing the occurrence of JFET effect, and solving the problem of low channel mobility. It has excellent performance such as low on resistance, low parasitic capacitance, and low switching energy consumption, and has significant cost and performance advantages. It has become the mainstream direction of silicon carbide power device development.

What are the advantages of SiC MOSFET over Si MOSFET Compared with Si MOSFETs, SiC MOSFETs have many advantages, including the following:

Detailed explanation of reverse recovery principle of silicon carbide (SiC) diode Silicon carbide diodes are unipolar devices, so compared to traditional silicon fast recovery diodes (silicon FRDs), silicon carbide diodes have ideal reverse recovery characteristics. When the device switches from forward to reverse blocking direction, there is almost no reverse recovery power, and the reverse recovery time is less than 20ns. Even the reverse recovery time of 600V10A silicon carbide diodes is less than 10ns.

Comparison of driving circuit differences between SiC MOSFET and Si IGBT SiC MOSFET and Si IGBT are both indispensable products for the development of electronic products. SiC MOSFET and Si IGBT have many common characteristics and differences. Therefore, the following is a comparison of their product differences:

The main six stages of SiC chip manufacturing The main six specific processes of SiC chip manufacturing are pre-processing, wafer processing, crystal growth, integrated circuit design and fabrication, chip testing, and integration.

SiC MOS driver design SiC MOS driver design is a complex process that requires consideration of many factors, such as electrical performance, thermal characteristics, and packaging selection. To improve reliability and performance, the following aspects should be considered:

The requirements for the driver board of SiC silicon carbide MOS dual pulse testing equipment are as follows: The requirements for the driver board of SiC silicon carbide MOS dual pulse testing equipment are as follows:
