TVS - Diodes

A Transient Voltage Suppression (TVS) diode is a solid state device that provides protection from high-voltage electrical transients such as electrostatic discharge (ESD). TVS diodes are designed to protect sensitive electronics from overvoltage caused by electrical transients.The MXLSMBJ40AE3 is a two-electrode transient voltage suppression diode that provides protection against ESD, lightning strikes, voltage spikes and surges. It is designed with a Zener region that clamps the voltage to a maximum of 40 volts when exposed to electrical transients. The device is also capable of absorbing up to 25A of current. It can be used for a wide range of applications such as automotive, communication, industrial and consumer electronics.

Application Field

The MXLSMBJ40AE3 is a versatile diode suitable for a wide range of applications. It can be used in automotive components such as airbag controllers, fuel pumps and other electrical systems. It can also be used in communication systems, such as radio transceivers, Ethernet cables and cable TV systems. The diode is also suitable for industrial and consumer electronics, such as PCs, tablets and mobile phones.

Working Principle

The MXLSMBJ40AE3 diode is a bi-directional diode that has a Zener region which can clamp the voltage to a maximum of 40V. When exposed to a transient voltage, the Zener region starts to conduct current and the excess voltage is dissipated as heat. The device is capable of absorbing up to 25A of current, making it a suitable protection device against overvolt spells.When the transient voltage is removed, the diode returns to its normal non-conducting state and the circuit is functional again. The device also has ESD immunity up to 15kV, making it a suitable component for use in high-voltage applications.In conclusion, the MXLSMBJ40AE3 is a two-electrode transient voltage suppression diode that is suitable for protecting circuits and components from overvoltage caused by electrical transients, such as ESD and lightning strikes. It can be used in a wide range of vehicles and consumer electronics, providing reliable protection and ESD immunity.
