SLD18U-017 TVS - Diodes Application Field and Working Principle

TVS-diodes, also known as Transient Voltage Suppression or Voltage Limited Diodes, are widely used in various electronic systems. They are mainly used for protection against electrical transients, which are short bursts of electrical energy, usually originating from a surge or spike in voltage or current. They are useful for protecting circuits from electrostatic discharge (ESD), electrical overloading, and voltage transients. There are a variety of TVS-diodes available on the market, with the SLD18U-017 model offered by Shanghai LianDa being one of the more prominent ones. In this article, we will cover the application field and working principle of the SLD18U-017 TVS-diode.The SLD18U-017 is a unidirectional diode that is used in a variety of applications, from protection against lightning strikes in industrial power systems to protection against voltage spikes in communications equipment. The device is capable of withstanding voltages up to 1.7 kilovolts while providing fast response times and low clamping voltages. This makes it a great choice for most applications that require protection against electrical transients.The main function of the SLD18U-017 is to provide protection against ESD, lightning strikes, current overloads, and voltage transients. When an electrical transient occurs, the device will act as a safeguard, diverting the excess electrical energy away from the electronic circuit and protecting the system from damage. The SLD18U-017 is specifically designed for applications where high energy transients need to be protected against.The working principle of the SLD18U-017 is fairly simple: when the diode is exposed to a high current or voltage, the device will divert the energy and protect the system in which it is used. The device is able to do this through its design, which consists of four elements: the diode itself, a reverse region, a reverse voltage region, and a current control region. When an overvoltage or overcurrent occurs, the reverse region will become active, diverting the energy away from the electronic system and preventing any damage to the system.The SLD18U-017 is a reliable and cost-effective choice for many applications, as it can provide fast response times, low clamping voltages, and protection against a variety of transients. Moreover, the device has a high peak pulse power rating, making it suitable for use in high-energy transient protection applications. The device is also shock and vibration tested, ensuring its reliability in most operating conditions.In conclusion, the SLD18U-017 TVS-diode is a versatile and dependable device that provides high-quality protection against ESD, lightning strikes, current overloads, and voltage transients. It is a great choice for many applications where fast response times, low clamping voltages, and reliable protection are required.
