MXLSMBJ70CA Circuit Protection

The MXLSMBJ70CA is a TVS diode, capable of protecting sensitive components from electrostatic discharge.

When the voltage (V) on the pins of the MXLSMBJ70CA exceeds the breakdown voltage (VBR), an avalanche breakdown process begins in which a large number of free electrons flow through the diode in the forward direction, dissipating the surplus energy as heat. This process continues until the voltage falls again below VBR, and the diode returns to its off state.

The MXLSMBJ70CA is typically used to protect high speed interfaces such as USB and HDMI from ESD damage. It is particularly suited for use in the automotive sector, where it can be used to protect components from damage due to the high voltage spikes that are often present in this environment.

The rated power dissipation (PD) of the MXLSMBJ70CA is 1.2W, which means it can dissipate up to 1.2W of power in the breakdown process. This power dissipation makes it suited for use as a protection device for sensitive components with a low power rating.

The MXLSMBJ70CA is also rated for a minimum breakdown voltage (VBRmin) of 70V, which means it can safely handle up to 70V of voltage. This makes it suitable for use in a wide variety of applications that are subject to high voltage spikes or surges.

In addition to its role as a protection device, the MXLSMBJ70CA can also be used as a fast-acting switching device. In this role, the diode can be used to switch current quickly, without the need for additional components or circuitry.

Overall, the MXLSMBJ70CA is a rugged, reliable, and cost-effective protection device that is well-suited for use in a wide range of automotive, electronic, industrial, and consumer applications.
