What is a TVS Diode?

A TVS Diode is a specialized form of semiconductor diode that provides electrical overvoltage protection by clamping operation. TVS (Transient Voltage Suppressor) diodes, also known as surge suppressor devices, clamp the voltage across a circuit when the voltage exceeds a specific voltage, called the rated breakdown voltage of the TVS Diode. Generally, a TVS Diode is less expensive than other components, and provides protection from a number of different types of electrical overvoltages, such as electrostatic discharge (ESD) or surge. TVS diodes are typically used in applications where the system needs robust protection from electrical overvoltage.

MXLSMLG15CA Application Field and Working Principle

The MXLSMLG15CA is a low-capacitance transzorber (TCFV) diode designed for applications requiring transient overvoltage protection. The device is designed for protecting off-line power supplies from detrimental voltage transients produced by lighting or switching transients. It features a lower capacitance than the standard transfer diode in order to meet the requirements of the latest generation of power supplies. The low capacitance of MXLSMLG15CA combined with its low capacitance bleed ensures that the device optimizes the response time to nuisance transients and provides high-performance ESD protection.

The MXLSMLG15CA is a bidirectional device that clamps the transient voltage to a low voltage level. When the transient voltage exceeds the breakdown voltage of the MXLSMLG15CA, an avalanche diode conducts the excess voltage to ground. This low voltage clamping action prevents system damage caused by large voltage transients. The MXLSMLG15CA also has a low capacitance bleed that allows it to rapidly dissipate the stored energy. This feature ensures that the MXLSMLG15CA provides reliable protection even from fast-rise transients which produce high peak currents and voltage changes.

The MXLSMLG15CA is well-suited for applcation in telecommunication, consumer electronics, industrial, automotive, and computer equipment. The device can also be used to protect sensitive data lines such as RS232, RS422 and CAN bus. In addition, it is suitable for use in receivers located near transmitters or in power supplies around digital switching. This device is extremely cost effective and reliable, making it an excellent choice for any application requiring ESD and transient overvoltage protection.
