TVS - Diodes: 5.0SMDJ18A application field and working principle

TVS - Diodes are becoming increasingly popular in the electronics industry. This is due to their ability to absorb transient surges of voltage and offer superior protection to various components. The 5.0SMDJ18A is one such TVS - Diode, and this article will outline its application field and working principle.The 5.0SMDJ18A are an 18V bi-directional, non-polar TVS - Diode that can be used for general-purpose transient voltage surge suppression in a wide range of applications. These applications include computing and communications equipment, consumer electronics, car electronics, industrial equipment, medical equipment, and a variety of other electronic devices.The 5.0SMDJ18A has a low reverse clamping voltage, making it ideal for a number of high environmental conditions and harsh weathers. Moreover, the 5.0SMDJ18A has its maximum let-through voltage at around 24V, meaning that it can protect devices from surges up to 24V of voltage. The 5.0SMDJ18A also has a lightning surge rating of twice the normal peak power and a peak clamping voltage of 42V for fast transient over-voltage protection.The working principle of the 5.0SMDJ18A is relatively simple. When a mounting surge of voltage passes through the 5.0SMDJ18A, it will temporarily increase the reverse leakage current and absorb the over-voltage protection. The larger the surge, the more voltage that the 5.0SMDJ18A will absorb. The excess energy is then dissipated as heat, ensuring the safety of the devices.The 5.0SMDJ18A also features a low capacitance, meaning that data signal distortion is greatly reduced. This is important for devices such as computer networks and communication equipment, which require precise and reliable data transmission. The 5.0SMDJ18A also has a low forward voltage which helps improve energy efficiency in a variety of devices.In summary, the 5.0SMDJ18A is an ideal solution for transient surge protection. Its low reverse clamping voltage makes it suitable for numerous harsh conditions and its low capacitance and forward voltage minimizes signal distortion and increases energy efficiency. The 5.0SMDJ18A is used in a broad range of applications from consumer and car electronics to industrial equipment and medical devices, offering excellent protection from transient surges.
