TVS (Transient Voltage Suppressor) diodes are some of the most important components in electronic equipment, because they are designed to protect the expensive components from any kind of sudden voltage spike in the connected power supply line. In particular, the SMCJ90A-TP is an Unidirectional TVS-Diode with 1500W Peak Power Dissipation and 0.5pF Clamping Voltage.

The application field of the SMCJ90A-TP is very broad and includes computers, industrial equipment, test equipment, power supplies and communication systems. It can be easily used in many automotive applications such as automotive electronic gates and turn signals, shock absorber systems and brakes, and vehicle security systems. In addition, the SMCJ90A-TP can also be used for protection against surges in power lines and other power applications, such as the protection of the very sensitive integrated circuits and other electronic components.

The working principle of the SMCJ90A-TP is very simple. The diode will instantly detect any sudden increase in voltage within the connected power line and divert it, subsequently preventing the connected components from suffering any damage due to the sudden voltage spike. It commonly works by quickly connecting a low resistance shunt across the power line and subsequently providing a safe conductive path for the surge current. This fast response of the diode to voltage spikes makes it an ideal choice for spike protection.

In addition to its durable self-recovery characteristics, the SMCJ90A-TP also features fast response time, excellent electrical clamping performance, and very low dynamic energy dissipation. It is also compliant with various international safety standards, such as the IEC 60068-2-27 standard.

More importantly, the SMCJ90A-TP is a highly reliable device which was designed to last for long periods of time. It features an average operating life of more then 50.000 hours, making it uniquely suitable for the operation in harsh environments exposed to extreme temperature and humidity.

In conclusion, the SMCJ90A-TP is an important and reliable component for the protection of electronic equipment against voltage-related incidents. Its wide application range and its long expected operating life make it an ideal choice for any electronic system.
