TVS - Diodes – SMX1J7.5A-TR Application Field and Working Principle

Surge protection devices, also known as TVS - Diodes, are an electronic component used to protect circuits from high-energy, fast transients, such as lightning strikes or electrostatic discharges (ESD). TVS -Diodes are typically designed to absorb the high-energy transient and divert the current away from the protected circuit, thus preventing permanent damage and providing a much higher level of protection. The SMX1J7.5A-TR is a solid state surge protector developed by Littelfuse that offers protection from high-energy transients overvoltages.

Application Field of SMX1J7.5A-TR

SMX1J7.5A-TR TVS – Diodes can be used for protecting all kinds of devices and circuits against high-energy transients, including computers, telecommunications equipment, power tools, automotive electronics, control systems, and any other electronic systems. It provides transient protection from most surge sources, including lightning, ESD, and various RF interference, allowing the protected devices to operate safely and reliably.

Working Principle of SMX1J7.5A-TR

The working principle behind the SMX1J7.5A-TR is simple and straightforward. The device includes a PN junction diode, which is triggered when the voltage across it exceeds the specified breakdown voltage. When this is the case, the device quickly and safely clamps the voltage and diverts the current to ground, thereby protecting the protected circuits from damage. In addition, the device also has a high surge current rating which allows it to absorb and dissipate more transient energy than other comparable devices.

Conclusion

The SMX1J7.5A-TR is an excellent device for protecting electronics from surges in voltage. It is easy to use, has a high surge rating, and is very reliable. It is suitable for a wide range of applications, including consumer electronics, telecommunications equipment, automotive applications, and many other electronic systems. With its reliable protection, the SMX1J7.5A-TR is an ideal surge protection solution.
