TVS (Transient Voltage Suppressor) diodes are unique semiconductor designs that protects sensitive electronic circuits from damage due to transient voltage. Among all the TVS diodes, MASMCJLCE64A is a special low capacitance bidirectional device with separate negative and positive transient suppression. While it increases device reliability, the working principle of MASMCJLCE64A based on its avalanche behavior.

As a series of device, the most typical application field of MASMCJLCE64A is tailored USB port protection. That is to say, in a USB port application, the insertion or withdrawal of a device can cause current and voltage transients or surges that lead to disruption of the system. Here, the MASMCJLCE64A devices are designed to clamp the induced voltage within an acceptable range so as to protect vulnerable circuit for further application.

Essentially, the working principle of MASMCJLCE64A lies in the internal avalanche breakdown mechanism. In essence, when the device is triggered by the input transient voltage signal, the avalanche effect converts the charge into a voltage across the device junction. As a result, the voltage clamp is achieved and the parasitic capacitance will be relatively low. Moreover, the low parasitic capacitance technology can maintain the signal integrity during the transient. Certainly, the direction of the transient voltage also plays a key role in triggering the avalanche effect, here the MASMCJLCE64A is bidirectional, enabling it to protect both positive and negative signals.

To sum up, the MASMCJLCE64A is a unique bidirecitonal device aiming to provide efficient protection in high speed and ESD sensitive ports. Compared to pervious devices, MASMCJLCE64A is ultra-low capacitance, allowing better signal integrity and ESD performance with minimal additional cost and board space. Moreover, the working principle of MASMCJLCE64A is based on its avalanche breakdown mechanism. In summary, due to its low capacitance and superior performance, the MASMCJLCE64A series of devices is becoming increasingly popular for tailored USB port protection.
