TVS (Transient Voltage Suppressor) diode is a device that functions as a regulator against induced transient voltage and surges. MXLSMBJ7.0A is the latest generation of TVSM diode and is specially designed for automotive applications, providing superior surge protection for sensitive components.

The MXLSMBJ7.0A is made up of a Silicon (Si) avalanche diode with a voltage rating of ±7 kV. This voltage rating clearly exceeds most automotive system requirements, making it an excellent choice for automotive applications. The MXLSMBJ7.0A has an integrated protection zone which covers most automotive applications, with low clamping voltage of 7V at peak pulse current of 2.5A. The additional capacitive features of the device ensure the full protection of sensitive board-level components from overvoltage damage.

The working principle of the MXLSMBJ7.0A is based on an avalanche chip that is designed to deform under the influence of voltage surge. This deformation creates a low-impedance barrier between the power supply and the device, thus providing short circuit protection to the connected equipment. When the voltage surge exceeds the normal operating voltage of the device, the avalanche chip is triggered, shunt the surge to the circuit’s ground. This process only lasts a few milliseconds, so it doesn’t affect normal operation of the circuit.

The MXLSMBJ7.0A is designed to work in a wide range of automotive applications, including electronic control units for engine management, electron ignition, fuel injection, ABS, airbag, and other power and safety related electronics. The device is also suitable for industrial applications, including automotive lighting systems, warning lamps, and telematics.

In summary, the MXLSMBJ7.0A is the latest generation of TVS diode specifically designed for automotive applications. It is based on an avalanche chip which deforms under the influence of voltage surge, creating a low-impedance barrier between the power supply and the device. Its high voltage rating makes it suitable for a wide range of automotive applications and industrial applications.
