A TVS diode is an electronic component designed to protect other electronic components from high voltage techniques. It is a combination of a diode, a resistor and a capacitor components in a single plastic package. The MXLSMCG58A is a multi-chip fast acting polymeric TVS diode specifically designed for surge and ESD protection applications in consumer and automotive electronics. It is designed to protect sensitive components from high-energy transients, and has a wide range of industry applications.

Application Field

MXLSMCG58A is suitable for IEC61000-4-2 level 4 (>±15kV air/±8kV contact ESD) protection and IEC61000-4-5 level 3 (up to 60A 8/20μs surge)protection. The device is also suitable to combine IEC61000-4-2 and IEC61000-4-4 (2kV/4kV CDM) surge protection requirements. The MXLSMCG58A is designed to protect electronics designs in the consumer and automotive electronics market.

The applications for this device include but are not limited to: automotive electronics, medical devices, audio/video systems, telecom and wireless applications, computer-related peripherals and peripherals exposed to lightning.

Working Principle

TVS Diodes stand for Transient Voltage Suppression Diodes. When over-voltage happens, the voltage barrier appears in the forwarding direction and the avalanche breakdown phenomenon occurs, which will convert the excess voltage into heat energy and suppress the voltage wave instantaneously. When the over-voltage disappears, the voltage barrier will return to be normal and the electric current can flow properly.

The Avalanche Diode (AVS) used in the MXLSMCG58A has a specially designed PN Junction for transient protection applications. It also has a built-in low resistance coating, which can improve the thermal performance of the junction point. This makes the protection response time of the MXLSMCG58A much faster than other TVS products.

The device is also equipped with an anti-surge or anti-ESD circuit, which helps protect the sensitive components of the system. The function of this circuit is to protect the system from overvoltage. When the voltage exceeds the rated voltage, the anti-surge circuit will disconnect the circuit, restricting the flow of current to the sensitive components, thus avoiding any unwanted damage to the system.

Other features of the MXLSMCG58A include a high clamping voltage to withstand transient surge up to 60A 8/20μs, low working voltage, low leakage current, high reliability, and low temperature coefficient.

Overall, the MXLSMCG58A is an ideal solution for surge and ESD protection applications for consumer and automotive electronics. It ensures that the system is well-protected against any unexpected high energy transients, and is designed to provide reliable protection.
