MBRM140T3G is a single high current rectifier diode from the diode family. Also known as Schottky diodes, these are most commonly used for the rectification of high current signals from DC sources. It has several advantageous features such as low forward voltage drop, fast switching time, low reverse leakage and a high voltage breakdown. The MBRM140T3G is used in a wide range of applications such as power supplies, power tools, motor drives, automotive electronics, solar cells and cell phone chargers.The basic working principle of a Schottky diode is the same as that of a regular diode, although there is a slight difference in the working characteristic. A Schottky diode is a p-n junction diode but its metal-semiconductor junction has the advantage of having a lower forward voltage drop. This provides higher current efficiency than a regular diode. The working of a Schottky diode can be divided into two parts, the forward bias and the reverse bias. When the MBRM140T3G is exposed to a DC voltage source, the anode is attached to the positive terminal of the voltage source and the cathode is attached to the negative terminal. In forward bias condition, current flows from the anode to the cathode through the diode and the voltage drop across the diode is equal to the forward voltage drop. This forward bias current is also known as the forward bias current characteristic. When a reverse bias voltage is applied to the MBRM140T3G, the anode is attached to the negative terminal and the cathode is attached to the positive terminal of the voltage source. In this situation, the voltage drop across the diode is equal to the reverse voltage drop. The diode remains off until the breakdown voltage of the diode is reached, and then current flows from the anode to the cathode, but at a much lower level than in forward bias. This reverse bias current is also known as the reverse bias current characteristic. The MBRM140T3G is a high current rectifier diode, meaning it has a greater forward current rating than a regular diode. This is due to its low forward voltage drop and high voltage breakdown. Its reverse leakage current is also low, which makes it an excellent choice for use in power supplies, motor drives, and cell phone chargers.In conclusion, the application field and working principle of the MBRM140T3G diode is of great importance in many fields like automotive, consumer electronics, power tools, and solar cells. Its low forward voltage drop and high voltage breakdown make it a great choice for high current rectification. Its low reverse leakage current adds to its advantages, making it a great choice for use in power supplies and motor drives.
