TVS – DiodesA transient voltage suppressor (TVS) diode is a key component in many electrical and electronic equipment systems designed to protect against sudden surges in voltage. The technology has been around since the 1960s, and in the decades since, it has become more and more essential for safety, reliability, and quality assurance. This article will provide a brief overview of TVS diodes, focusing on their 1.5KE10HE3/73 application field and working principle.A TVS diode is a special type of zener diode that is designed to protect against voltage spikes. As opposed to a regular zener diode, which is limited to a specific position in an electrical circuit, a TVS diode is designed to be added to an existing circuit for protection. It is not placed as a part of the function of a circuit, but rather as a safeguard against faults or overloads.TVS diodes use an avalanche breakdown mechanism to clamp voltage spikes and provide protection against overvoltage transients. An avalanche breakdown occurs when an electric field overcomes the reverse electric field threshold, allowing a current to surge suddenly and explosively. This current break can cause serious harm to circuits and even dangerous, sometimes even fatal, results for the users of the equipment. TVS diodes can be used in a variety of applications, including protecting electronic equipment from lightning strikes, transient industrial power faults, and electrostatic discharges (ESDs) in data terminals. As mentioned above, the 1.5KE10HE3/73 is a specific type of TVS diode, and it is designed to protect circuits from high-frequency spikes up to 8kV. It is built with a low-leakage current and low capacitance for high-speed switching applications, making it a great choice for protecting against high-frequency transients.When it comes to the working principle of the 1.5KE10HE3/73, the diode is designed to protect against transient overvoltages by clamping voltage spikes to a manageable level. When the voltage level reaches or exceeds a certain threshold (the rated breakdown voltage), the diode conducts an avalanche current, allowing a high current load to be transferred quickly to the ground and preventing the voltage from going too high. This is done in the fastest possible time, providing maximum protection against damaging overvoltage transients.To sum up, TVS diodes are invaluable components that provide effective protection against voltage surges from overvoltage transients. The 1.5KE10HE3/73 is a type of TVS diode that is particularly well-suited for high-frequency applications, and its principle of operation is based on the principle of avalanche breakdown. It is designed to clamp voltage spikes to a manageable level and protect electronic components from damage or destruction. With its robust design and fast response time, the 1.5KE10HE3/73 is an excellent choice for protecting against voltage transients and ensuring safe operation of electrical and electronic equipment.
