TVS - Diodes

Transient Voltage Suppressor (TVS) Diodes are designed to protect sensitive electronic components from voltage surges. In the event of an electrical surge, the TVS Diode will conduct current through it and reduce the voltage across the sensitive electronic components. The CD214A-T18CALF is an example of a TVS Diode. This article will explain the application field and working principle of the CD214A-T18CALF.The CD214A-T18CALF is an axial-leaded TVS Diode. It can handle voltages up to 18 Volts and can conduct up to 18 Amps of current. This makes it ideal for a wide range of applications, such as automotive, industrial, communication and consumer electronics. It is designed to protect sensitive electronic components from electrical surges, such as electrostatic discharge (ESD).The working principle of a TVS Diode is simple. When an electrical surge passes through it, it will conduct the current and reduce the voltage across the sensitive electronic components. It does this by allowing electrons to flow through it like a conventional diode. It also has a special breakdown voltage that is higher than the normal diode, which allows it to conduct more current. For the CD214A-T18CALF, this breakdown voltage is 18 volts.The CD214A-T18CALF\'s construction consists of two major components: a semiconductor junction and a passive resistor. The semiconductor junction is made up of two doped semiconductor materials, a p-type and an n-type. When a voltage is applied to the diode, a junction barrier forms between the p-type and n-type material, creating a depletion region. This region prevents current from flowing until a certain voltage is reached. When this voltage is reached, the depletion layer disappears and current begins to flow. The passive resistor is then used to control the current flow and prevent it from becoming too large.In summary, the CD214A-T18CALF is a TVS Diode that is designed with an optimized combination of high clamping voltage and low let-through current for protecting sensitive electronic components from voltage surges. It is constructed with a semiconductor junction and passive resistor, and has a breakdown voltage of 18 volts. Its wide voltage range and high current ratings make it suitable for a variety of applications.
