Introduction

TVS - Diodes are becoming an increasingly important part of modern power system designs. They are composed of an array of semiconductor diodes that are used to protect sensitive electronic components, such as computer components, from electrical surges. The MR2520LRL is a low leakage current, low resistance TVS diode designed to protect against transient overvoltages that could occur in high-speed, high-accuracy power systems. In this article, we will take a look at the application fields and working principles of the MR2520LRL.

Application fields

The MR2520LRL is designed for applications requiring high speed and power accuracies. It is typically used in applications like high frequency switching, digital signal processing, analog to digital conversion and brushless or stepper motors. This diode is also suitable for applications such as power supplies, signal line protection, audio amplifiers, and CCTV cameras.

Working principle

The MR2520LRL is a very robust TVS diode. It features low on-state resistance, fast response time and excellent clamping capability. When a transient voltage surge occurs, the diode intercepts and quickly dissipates the voltage, preventing its negative effects. The diode is composed of a semiconductor junction that acts as a switch between two terminals, the anode and the cathode. When a voltage spike is detected, the diode will switch on and the voltage will be clamped at a safe level. This clamping action is the result of the positive temperature coefficient of the semiconductor junction. This means that when the junction temperature rises, the junction resistance increases, thus limiting the current that can flow through the diode. The MR2520LRL has a low breakdown characteristic which means that even if the transient voltage exceeds the clamping limit, the diode will still not break down. This is because the leakage current is very low, meaning that the voltage is clamped at a lower level than it otherwise would be.

Conclusion

The MR2520LRL is a low leakage current, low resistance TVS diode designed to protect against transient overvoltages. This diode is designed for applications that require high speed and power accuracies and is composed of a semiconductor junction that acts as a switch between two terminals. When a transient voltage surge occurs, the diode intercepts and quickly dissipates the voltage, preventing its negative effects. The leakage current of the diode is low, making it an ideal choice for any power system design.
