TVS – Diodes are designed to help protect the circuit from transients that dictate fast rising voltage, while they can also help protect from surges or more evident spikes. By absorbing this energy and clamping the voltage, the diodes help to protect against whatever excessive voltages may enter the system. One of the common options for a TVS diode is the PGSMAJ85AHM2G

Application Field:

The PGSMAJ85AHM2G is most commonly used in industrial automotive-based ESD and Automotive EMC control applications, such as automotive infotainment systems. It has the capacity to absorb up to 20A of 16V power or 8A of 32V power. This makes it a good option for situations with high power demands and a high potential for transients.

Working Principle:

TVS diodes like the PGSMAJ85AHM2G are designed to activate when a voltage exceeds the specified breakdown voltage. In this case, the specified breakdown voltage is 8V. When this occurs in an automotive application, such as an infotainment system, the TVS diode will pass the transient current to protect the system from too much voltage entering.

The TVS diode acts as a sort of shock absorber, absorbing the excess voltage and thus protecting the system against damage or malfunction. It can also help prevent static electricity from reaching the delicate electronics within the system, helping to ensure that the circuits will remain functional.

TVS diodes have become popular, as they offer an effective and reliable line of defense for systems that could be otherwise vulnerable to transients or voltage spikes. The PGSMAJ85AHM2G has proven to be a reliable option for automotive infotainment systems, as it can effectively protect the system from transients without sacrificing power, or affecting the system’s performance.
