MXSMCJ78A Circuit Protection

TVS-Diodes are designed to protect sensitive electronic systems from destructive spikes in voltage. The MXSMCJ78A is one such device that uses its over-voltage protection function. This article will explain the application field and working principle of the MXSMCJ78A.

The MXSMCJ78A is designed primarily for use in surge suppressors and for short-term pulse operation protection up to 600W. This makes it an ideal choice for use in industrial applications, such as power supplies, locomotives, inverters, as well as automotive systems and communications systems. It can also be used effectively for consumer electronics, medical devices, and other circuits that require protection from voltage spikes.

The MXSMCJ78A is a dual breakover switch with a simple yet reliable design. It consists of two separate switches that are interconnected and actuated by a single voltage source. This allows for a single triggering voltage to initiate a breakover of the two switches, allowing for protection of the circuit from over-voltage. The two switches also work in concert, so that once one switch has broken over, the other follows and completes the protection circuit.

When the voltage increases beyond the triggering level, the MXSMCJ78A activates its two switches, both of which rapidly actuate to allow voltage to pass through the circuit while providing protection from the over-voltage. This rapid actuation and voltage protection occurs for both high and low voltage conditions and can be tailored to the specifications of the application by altering the triggering voltage levels.

The MXSMCJ78A is also designed with a fail-safe feature. If either switch fails to break over, the other will take over, ensuring that the circuit is still protected. This fail-safe feature eliminates the need for redundant switching and increases the reliability and longevity of the device.

The MXSMCJ78A is a reliable choice for surge protection and voltage spikes, and is suitable for use in many applications. Its dual breakover switch design ensures the safety of the circuit, while its fail-safe feature adds an extra layer of security. By tailoring the triggering voltage levels, the MXSMCJ78A can provide the exact level of protection needed for a particular application. Above all, the MXSMCJ78A is an excellent choice for surge protection and voltage spikes.
