Transient Voltage Suppressor Diodes (TVS), comprises a variety of different components that protects electronic equipment from excessive voltages caused by lightning, electrostatic discharge (ESD) and other applications. The MXSMCJ85CA is one such device. This article will provide a description of the application fields and working principle of the MXSMCJ85CA.

The MXSMCJ85CA is a unidirectional TVS Diode that is designed to protect sensitive electronic components from transient voltage overshoots. It is designed to protect against high voltage, fast transients (caused by lightning and high energy events) and has a breakdown voltage of 8.5V and maximum standoff voltage of 7.5V. The MXSMCJ85CA packs with a unique high-voltage protection technology with two diodes connected in reverse parallel (anti-parallel) between two lead pins. A surge protection plan designed with the MXSMCJ85CA will also protect against ESD and other low-level protection events as well.

The application fields of the MXSMCJ85CA include automotive systems such as ECUs and sensors, batteries, telecom networks and appliances, office machines, consumer electronics, industrial control systems, LED lighting, renewable energy systems and more. In automotive systems, for example, the MXSMCJ85CA provides protection against ESD, load dump, and other transient voltage overshoots. In telecommunication networks, the MXSMCJ85CA can protect against lightning and power surges. In LED lighting, the MXSMCJ85CA can protect against light emitting diodes (LEDs) from transient voltage overshoots.

The working principle of the MXSMCJ85CA is that when a voltage surge, spike or electrostatic discharge (ESD) is applied to the device, the breakdown voltage at which the diode "turns on" is reached. When this happens, a portion of the surge is dissipated by the diode. This purpose of this is to keep the voltage that is supplied to the protected load in a safe range. As a result, when an overvoltage is applied, the current is diverted away from the protected load. In the event of a sustained overvoltage, there is a reverse leakage current that flows from the terminal to the diode\'s cathode, that will then reduce the voltage until it returns to a safe rating.

The MXSMCJ85CA is designed with a robust construction that is capable of withstanding harsh environmental conditions such as vibration, shock, humidity, and extreme temperatures. It features superior temperature and humidity resistance, making it ideal for protecting against voltage surges in high-stress environments. The working temperature of the MXSMCJ85CA is -55C to 125C, with a maximum peak pulse current of 600A.

The MXSMCJ85CA is an efficient and robust device that is designed to protect against voltage transients and surges. It has a breakdown voltage of 8.5V and a maximum standoff voltage of 7.5V, has a wide range of applications including automotive, telecom, LED lighting, industrial and more, and is designed to withstand extreme temperatures and humidity. The working principle of the MXSMCJ85CA allows it to protect the load against excessive voltages caused by lightning, ESD, and other transient events.
