Diodes - Zener - Single: SMAZ22-13-F Application Field and Working Principle

The SMAZ22-13-F is a single diode-zener diode with an extended application field. It is commonly used for high-voltage and low-power applications, including ESD protection. It is designed with a low breakdown voltage and a high peak reverse current capability, allowing for efficient power distribution and reliable protection from transient voltages.The SMAZ22-13-F is a three-legged single diode-zener configuration with one galvanically isolated negative terminal and two galvanically isolated positive terminals. The reverse-acting zener diode serves as a switch, opening the diode when a certain breakdown voltage is reached and blocking the flow of electricity when the voltage goes beyond the limit. It is designed to be used in applications requiring a high reliability, low breakdown voltage, and high peak reverse current capability.The SMAZ22-13-F has an extremely low snap voltage and a very small forward voltage drop which makes it suitable for use in applications with a wide range of operating voltages. It also has a high peak reverse current capability, ensuring that it can withstand surges in transient voltages and still perform reliable protection from overvoltage.In terms of applications, the SMAZ22-13-F is extensively used as an ESD protection device in high-voltage and low-power applications. It is particularly suitable for applications such as overvoltage protection, overcurrent protection, current limiting, and signal protection. Additionally, the high peak reverse current in conjunction with the low breakdown voltage allows the device to handle high reverse voltages. As such, it is ideal for protecting signal paths, critical components, and circuit boards from overvoltage transients.The working principle of the SMAZ22-13-F is dependent upon the breakdown voltage specified in the datasheet. When the applied voltage exceeds the breakdown voltage, the diode opens and will allow current to pass through as long as the voltage is held at or above the zener breakdown voltage. Once the voltage is reduced below the zener breakdown voltage, the current through the device ceases and the diode acts as an insulator, blocking the current from flowing.The working principle of this single diode-zener device can be further divided into two distinct categories: diode conduction and zener conduction. During diode conduction, current flow is limited by the forward barrier voltage, which is equal to the zener breakdown voltage minus the device\'s reverse current rating. During zener conduction, the current flow is limited by the device\'s zener breakdown voltage rating, which allows higher peak currents to flow.In addition to its application in ESD protection, the SMAZ22-13-F is suitable for a wide range of other applications. It can be used in power supplies and line regulation circuits, as well as in transient protection circuits and logic circuitry. Its low breakdown voltage and high peak reverse current capability makes it a reliable and efficient solution for transient voltage protection.In summary, the SMAZ22-13-F is a single diode-zener diode with an extended application field. It is commonly used for high-voltage and low-power applications, such as ESD protection, power supplies, line regulation, transient protection, and logic circuitry. It is designed with a low breakdown voltage and a high peak reverse current capability, allowing for efficient power distribution and reliable protection from transient voltages.
