Introduction to TVS - Diodes

Transient Voltage Suppressor Diodes, commonly referred to as TVS-Diodes, are used in transient voltage protection to prevent damage from high-energy spikes or surges. These are typically inaccurately labeled voltage clamping devices, since the primary function is to limit the amount of current that can flow through them. They work by absorbing the energy of the surge and dissipating it.TVS-Diodes provide protection from high-energy spikes and surges in power, data, or telecommunications lines. They are a cost-effective alternative to expensive, bulky, and complex surge protectors. TVS-Diodes are also used in a variety of other applications, including industrial controls, medical equipment, automobiles, and aerospace.

5KP18CA Application Field and Working Principle

The 5KP18CA is a popular, inexpensive, and widely-used TVS-Diode specifically designed to suppress transients and surges on power and data lines. 5KP18CA devices are commonly used in applications such as domestic appliances, insect zappers, temperature controls, and automotive circuits.5KP18CA devices consist of a single, low-impedance diode connected in series with a stainless steel junction. The stainless steel junction dissipates the energy of the surge, while the diode then acts as a voltage clamp, preventing the energy from passing through the device.5KP18CA TVS-Diodes are capable of suppressing up to 18V of transient voltage and can handle surge currents of up to 18A (with insertion loss of 0.2ohm). The 5KP18CA is also rated for an operating temperature range of -55°C to 150°C, making it suitable for use in a wide variety of applications.

Conclusion

TVS-Diodes are an invaluable tool for protecting sensitive circuits and components from high-energy transient voltage and surge currents. The 5KP18CA is an inexpensive and widely-used device that is capable of providing protection up to 18V and 18A with minimal insertion loss. It is suitable for use in a variety of applications, including domestic appliances, insect zappers, temperature controls, and automotive circuits.
