Silicon carbide is a semiconductor material with excellent properties, and its application in the semiconductor field has attracted more and more attention. Next, we will introduce the characteristics, advantages and application scenarios of silicon carbide in detail, highlighting its important role and value in the semiconductor industry. First, the basic properties of silicon carbide. Silicon carbide is a high-temperature corrosion-resistant alloy material with high hardness, high thermal stability, and high electrical conductivity. At the same time, silicon carbide also has low resistivity and high breakdown field strength, which makes it have broad application prospects in high-performance fields such as high temperature, high pressure, and high frequency.
With the continuous advancement of science and technology, power transmission systems have increasingly higher requirements for reliability and efficiency. The emergence of silicon carbide MOS products has brought more outstanding performance to the power transmission system. Silicon carbide MOS products are high-efficiency, low-power power semiconductor devices with excellent characteristics such as high breakdown field strength and low turn-off loss. They can withstand higher voltages and larger currents, thus ensuring higher Power transmission efficiency and longer service life. Compared with traditional Si MOSFETs, SiC MOS has higher breakdown field strength and better high-voltage withstand performance, and can maintain lower turn-off current in a wider operating voltage range, thereby reducing the power consumption of the device and heat loss, improving the efficiency and reliability of the equipment. Silicon carbide MOS products are widely used in power transmission systems, frequency converters, inverters, motor controllers and other fields. In terms of power transmission systems, silicon carbide MOS products can effectively improve the efficiency and reliability of power transmission, thereby reducing energy consumption and losses. In the fields of frequency converters and inverters, silicon carbide MOS products can realize high-efficiency, low-noise, and low-power consumption control circuits, providing a strong guarantee for the high performance and high reliability of equipment. In terms of motor controllers, silicon carbide MOS products can achieve efficient, energy-saving, and environmentally friendly production methods through precise control of motors.
Schottky diodes are indispensable electronic components. Due to their important role in short-circuit protection, they are particularly indispensable. As we all know, when selecting a Schottky diode, the key is to look at its forward conduction voltage drop and reverse conduction voltage. Resistant to pressure, reverse leakage current, etc. But we rarely know how it is related to different currents, different reverse voltages, and different ambient temperatures. Knowing this relationship in circuit principles seems extremely important for choosing a diode that suits you, especially on the output power circuit board. Understanding its performance will make us more comfortable in our applications. The following article will take you to explore the characteristics of mysterious diodes. 但是我们其实很少了解它在不一样电流、不一样反向电压、不一样环境温度中的关联是怎么样的，在电路原理中知道这个关联对选择适合自己的二极管看起来极其重要，尤其是在输出功率电路板上。了解其性能，对我们的应用也更游刃有余，下边本文带您你一起去探寻神秘二极管特点。 正方向导通压降与导通电流之间的关系 在肖特基二极管两边加正方向偏置电压时，其内部结构静电场地区变小，能够有非常大的正方向蔓延电流根据PN结。 只有在正向电压做到某一标值(这一标值称之为“门坎工作电压”，锗管大约为0.2V，硅管大约为0.6V)之后，二极管才能做到真正导通。 但肖特基二极管的导通压降是稳定永恒不变的吗?它和正方向蔓延电流又存有什么样的关系?根据下面的图的检测电源电路在常温对型号规格为SM360A的二极管开展导通电流与导通压降的关系测试，可获得所显示的线条相互关系：正方向导通压降与导通电流正相关，其波动压力差为0.2V。 从负载导通电流到额定值导通电流的压力差虽仅是0.2V，但是对于输出功率肖特基二极管而言它会严重影响高效率还会影响肖特基二极管的温度，因此在价钱有条件的话下，尽量选导通压降小、额定值工作中电流较具体电流高一倍的肖特二极管。
