SMCJ85A is a silicon-based TVS (transient voltage suppressor) diode. It is designed to protect sensitive circuits such as microprocessors, logic chips and data lines against electrical surge. It is designed to protect the equipment from high voltages and transients in the range of 1kV to 3.4kV. The SMCJ85A can be used in a wide range of applications such as automotive, telecom, consumer electronics and medical instruments.

The SMCJ85A is a unidirectional transient voltage suppressor diode. It has an avalanche breakdown voltage of 5V and a peak pulse power of 1.5kW. The package is a SOT-23 and the device is RoHS compliant. It is able to protect up to two I/Os in any combination to IPP3. It is also designed to cope with power line disturbances (PLDs) that may occur in the industrial and medical field. The device is designed to handle up to 6kW ESD and 500W EFT.

The SMCJ85A is easy to use and is considered to be a low power solution. It is able to protect three I/O lines with a minimum line voltage of 6V. The device can operate over a temperature range of -55 to 125°C. The device has an optocoupler feedback that provides feedback on its operating conditions. This type of feedback can help a system maintain a stable level of protection by providing data on any surge or transient that may be occurring in the circuitry.

The working principle of the SMCJ85A is based on the principle of breakdown voltage. When the voltage across it exceeds its breakdown voltage, the device will begin to conduct current, dissipating the surge in a controlled manner, thereby protecting the underlying circuit. This type of protection is an important tool in ensuring the safety of the system from any transient event or high voltage surge. As the device is able to dissipate the surge in a controlled manner, it can reduce the amount of electrical damage that the equipment may sustain.

The SMCJ85A can be used in a variety of applications such as automotive, consumer electronics, industrial, medical and telecom. In automotive applications it is used to protect microprocessors, lighting and diagnostic systems from electrical surge. In the telecom and consumer electronics field, it is used to protect sensitive electronic equipment from power surges and transients. In industrial applications, it is used to protect against power line disturbances. In medical applications, it is used to protect vital medical equipment from transients.

The SMCJ85A is a robust device that is able to protect a wide range of electrical equipment from transient voltage. It is able to protect two I/O lines with a minimum input line voltage of 6V, making it ideal for a variety of applications. With an optocoupler feedback, it is able to provide protection against transients and power line disturbances. With its wide range of operating temperatures, it is suitable for a variety of applications.
