Introduction

SA7.5 is a kind of transient voltage suppressor (TVS) Diode, which has many excellent electrical performance, such as superior surge capability, high reliability, small size, etc. These features make it a widely used component for multiple applications.

Features and Applications

SA7.5 contains 15V uni-directional, 30V bi-directional, and 600W peak stand-off voltage TVS chips. It is specially designed for overvoltage protection of sensitive and critical circuits due to the surge voltage. In general, it is used in consumer electronic products, automotive electronics, industrial equipment and opto-electronic applications.

Working Principle

SA7.5 is basically an diode, also called a unidirectional amplifier. When the voltage across it is reversed, the diode will start to conduct current. Therefore, the voltage across it will decrease, resulting in an conduction equal to the excess voltage.

When there is an over-voltage surge event, the TVS diode will quickly absorb the surge energy and divert it harmlessly, thereby protecting the electronic components and circuits beyond it. This is done by leveraging the diode\'s superior surge absorption capability to clamp the voltage down to a safe level.

SA7.5 also has a fast response time. This ensures quick reaction to transient surge events, making it one of the most reliable surge management solutions for various applications.

Conclusion

SA7.5 is a TVS diode that is widely used in various applications due to its superior electrical performance and high reliability. Its working principle is the same as that of a regular diode, but it has the advantage of quick response time, which makes it a great solution for protecting circuits from voltage surges.
