TVS - Diodes: Application Field and Working Principle

TVS or transient voltage suppressor diodes are components used in all kinds of electronics equipment to protect sensitive circuits from voltage spikes. They are small devices that absorb extra voltage surges and can save your equipment from damage. With its low leakage current, fast response time, and high-voltage capability, a transient voltage suppressor diode is an essential component for most electronic circuits.TVS diodes are used in a wide range of applications ranging from high-end communication and industrial equipment to consumer electronics. They are primarily used in electrical power systems to protect circuits from destructive surges of high voltage caused by lightning, sudden power outage, switching surge, and other abnormal events.

Working Principle

TVS diodes are based on the zener diode principle, which is based on the principle that when the forward voltage or current of a diode is increased to a certain value, its current will start to flow in the reverse direction. This is called reverse breakdown phenomenon and it is utilized by TVS diodes to limit the voltage of a circuit.TVS diodes can be divided into two types, depending on the type of breakdown phenomenon: avalanche breakdown and Zener breakdown. At high voltages, the avalanche breakdown type diodes are capable of absorbing large energy bursts, while the Zener breakdown type diodes provide consistent protection in the presence of a specific breakdown voltage.

Application Field

TVS diodes are commonly used for all kinds of motors, appliances, and other devices that require protection from voltage and current spikes. They are used in consumer electronics such as cell phones, laptop computers, and gaming systems; in industrial automation and communications systems, for surge protection and lightning protection; and in automotive electronics.TVS diodes are also used in high-end radio systems where they protect from overvoltages caused by transmitter switching surge. In this case, the diodes protect the radios from being damaged by wide-spectrum incoming signals.In the medical field, TVS diodes are also used in hospital equipment to protect against voltage spikes. They are also used in implantable pacemakers and other implantable medical devices, where they prevent electric shocks in the body due to voltage surges.To summarize, TVS diodes provide a vital function in electronic circuits, by protecting circuits from damage due to voltage and current spikes. They are used in a wide range of applications, from consumer electronics to industrial and medical equipment. They can be divided into two types, based on the kind of breakdown phenomenon and can be selected according to the specific requirements of the circuit.
