1N1128AR

Introduction

1N1128AR is a kind of single rectifier diode. It is specially designed with a common anode, which is suitable for use in low voltage and high current applications. In this article, we will discuss its application field and working principle.

Application

1N1128AR is primarily used for rectification and signal isolation in automotive, medical and industrial applications. In automotive applications, its low forward voltage drop helps reduce power consumption and increase efficiency. In medical applications, its low forward voltage drop and low reverse leakage current helps ensure reliability and medical safety. In industrial applications, it can be used for variable power input, signal isolation and wave shaping. Generally, it is suitable for low voltage and high current applications.

Working Principle

The 1N1128AR rectifier diode is made up of two leads, a positive lead, called the anode and a negative lead, known as the cathode. When a positive potential is applied to the anode side, current flows through the diode, while when a negative potential is applied to the anode side, current will not flow through the diode. This is the principle of diode rectification. The 1N1128AR is a single diode so it will only allow current to pass in one direction.

When the voltage across the anode and cathode of the 1N1128AR exceeds the threshold voltage, the diode will turn on and allow current to flow from the anode to the cathode. The threshold voltage for the 1N1128AR is usually around 0.6V. This is known as the forward voltage drop. The larger the forward voltage drop, the more efficient the diode will be.

On the other hand, when a negative voltage is applied to the anode side, the diode will be in the “off” state. The current will not flow from the anode to the cathode, but instead a small amount of current will flow from the cathode to the anode. This is known as reverse leakage current, and is an important factor to consider when selecting a diode for an application.

Conclusion

In conclusion, the 1N1128AR single rectifier diode is a versatile, efficient and reliable device suitable for a variety of applications. Its application field mainly includes automotive, medical, and industrial applications, and it works by passing current in one direction, while blocking current from passing in the other direction. Moreover, its low forward voltage drop and low reverse leakage current are important characteristics to consider when selecting it as a component for an application.
