The MXSMBJ13A is a unidirectional 600 watt TVS diode that provides transient suppression over a wide range of operating voltages. This component is a dual diode package, with one side connected in reverse and the other side connected in forward. It has low capacitance and fast switching capabilities, making it ideal for applications that require high speed switching. Since it has excellent thermal characteristics, it is suitable for applications where high power dissipation is required.

The MXSMBJ13A is a surface mount component that is ideal for use in a variety of applications including power supplies, motor controllers, LED drivers, embedded controllers, and automotive ECUs. Its package size is only 4mm x 3.6mm, making it small enough to fit in highly confined areas. The operating voltage range is from 6V to 160V and the peak pulse power rating is 600 watts. The maximum surge current rating is 20A and the maximum clamping voltage is 33V.

The working principle of the MXSMBJ13A TVS diode is based on the theory of avalanche breakdown. When connected in reverse, it operates in avalanche breakdown mode. When a large voltage is applied to the junction, the carriers present in the junction are accelerated to a high speed. When these carriers reach a high velocity, their energy is large enough to cause further ionization of the carriers in the junction, resulting in an avalanche breakdown. This breakdown rapidly generates a large amount of current that clamps the voltage across the junction. In forward biased mode, the diode acts as a conventional diode, allowing current to flow from anode to cathode.

The MXSMBJ13A TVS diode is designed to provide transient protection in applications where fast response time and excellent thermal characteristics are desired. It is also well suited for ESD and surge event protection. All of its features make it an ideal option for use in a wide range of applications.
