Introduction

Transient Voltage Suppression (TVS) diodes are used in a wide variety of applications and can provide protection to electronic devices from various types of high voltage surges. The MXLSMLG20CA is an N-channel junction array for switching loads up to 25mA.

Application Fields

The MXLSMLG20CA TVS Diode can be used in a broad range of consumer, industrial and automotive electronics. Its ESD protection, safe operating area protection, and low stand-by current make it a perfect choice for those applications in which minimal power consumption is required. It has excellent clamping characteristics and is specifically designed for automotive environments. In addition, its low profile package allows for easy design-in and small welding area.

Automotive applications can include the protection of vehicles against transient voltage surges. The MXLSMLG20CA provides protection from transients that may be caused by the connection/disconnection of a power source and can protect automotive devices from short circuit, overload, and ESD damage.

In the industrial IoT field, the MXLSMLG20CA can be used to protect devices from voltage spikes, ESD, and transients. Industrial applications can include any type of IoT device, such as motor controllers, controller interfaces, dedicated IoT devices, and even be used in medical devices.

In consumer electronics, the MXLSMLG20CA can be used to protect consumer facing devices from short circuit, overload, and ESD. TVs, tablets, laptops, and phones can all benefit from the protection offered by the MXLSMLG20CA.

Working Principle

The MXLSMLG20CA is an N-channel junction array designed to switch loads up to 25mA. It is designed to protect vulnerable electronic components from the damaging effects of voltage transients by clamping the voltage at a safe level.

The working principle can be described as follows: When a voltage transient (most commonly an increased voltage value) is applied to the diode, the PN junctions within the diode become forward biased and electrons start to flow. As the voltage exceeds the diode\'s breakdown voltage (VBR), the electrons will flow into the junction until the voltage level is equal to the diode\'s maximum junction voltage. At this point, the current stops flowing until the voltage drops back below the VBR.

The MXLSMLG20CA has a reverse breakdown voltage of 15V and a maximum junction voltage of 40V, which provides a wide range of protective coverage from most common transients. Additionally, the MXLSMLG20CA has a low stand-by current of 100nA and can provide up to 25mA of short circuit protection.

Conclusion

The MXLSMLG20CA TVS Diode is a multi-use protection device which can be used in various automotive, industrial, and consumer electronics applications. Its low VBR and maximum junction voltage provide a wide range of coverage for transient protection. Additionally, its low stand-by current and 25mA maximum switch current make it a perfect choice for those applications in which low power consumption is needed.
