Friends who are doing circuit design will be familiar with TVS transient voltage suppression diodes. Their main function is to protect sensitive components and circuits from damage by high-voltage transients. In recent years, an advanced flyback TVS has gradually entered everyone's field of vision.

The biggest difference between the so-called flyback TVS and the traditional TVS is that when the voltage reaches the trigger voltage, the clamping voltage at both ends of the device will be instantly lowered to between the operating voltage and the trigger voltage, and then the voltage will gradually increase as the current increases. Increase (as shown below). This characteristic makes the flyback TVS have an extremely low clamping voltage ratio, which can suppress the transient voltage at a lower clamping voltage, help release energy in advance, greatly protect the safety of IC and downstream circuits, and effectively Reduce the residual pressure value of the rear end.

Do you want to learn more about such a unique circuit protection component? The following technical white paper will take Vishay's flyback XClamp R ^TM TVS as an example to explain the principles, characteristics and advantages of flyback TVS, and the value it can bring to your design, including:
