TVS - Diodes Application Field and Working Principle

TVS-Diodes, or Transient Voltage Suppression Diodes, are specialized diodes used to protect sensitive electronic components from electrostatic discharges, voltage surges, and other transient circuits. They are used to provide protection against harmful transients such as electrostatic discharge (ESD), induced electrical overstress (EOS), lightning-induced surges, and other elevated potential pulses. They are designed to clamp offfast rising transients and to limit high-frequency noise.The SMAJ17CA-13-F is a unidirectional transient voltage suppressor diode, which is a type of TVS diode. It enables protection for equipment from transient surges of up to 17V. They are typically used on a printed circuit board, and with their low maximum standoff voltage and low clamping voltage, they can effectively protect delicate integrated circuits (ICs) from over-voltage transients.An SMAJ17CA-13-F, typically packaged in a SMAJ Surface-Mount Package, is an 18mm2 hermetically sealed, axial-leaded diode. It has a rated working peak reverse voltage of 17V, and a maximum standoff voltage of 8.3 Vdc. It is especially designed to provide protection against ESD, surges, and other transient voltage threats. The low clamping voltage makes it an ideal choice for sensitive electronic components with low withstand voltage, like ICs, as it reduces the potential to cause permanent damage to the component.The SMAJ17CA-13-F works by clamping the transient voltages whenever there is an over-voltage surge. A transient voltage is a type of voltage surge where a voltage meets a fast rising transient — a few microseconds to a few milliseconds in duration. The SMAJ17CA-13-F limits the voltage by clamping the surge within a range that the delicate electronic components, like ICs, won’t be damaged.The working principle of the SMAJ17CA-13-F is simple. It has a reverse breakdown voltage, also known as the standoff voltage, and a reverse triggering voltage. When circuit current reaches a value which is equal or greater than the triggering voltage, the diode starts to conduct and limits the voltage that reaches the protected device. This process transfers the current path from the protected component to the diode and discharges the voltage. The SMAJ17CA-13-F is a valuable component to include in any circuitry, as it is an important device for protecting a variety of electronic components, including ICs. It helps protect sensitive components from over-voltage transients and ESD, potentially saving both time and money. Additionally, since their operating principle is quite simple and they come in a variety of packages, TVS diodes can be used easily, making them a reliable and cost-effective protection solution.
