Transient voltage suppressors (TVS) are devices designed to protect electronic and electrical components against damage due to transient overvoltage events. They limit the voltage applied to a protected part or system during overvoltage and undervoltage events, while providing a low breakdown voltage and a fast response time when compared to other protection devices. The SA26CA-B TVS diode is a two-terminal unidirectional device used to protect against high voltage transients and surge currents. It is an ultra-small diode for protection in harsh environments where space is limited.

The SA26CA-B is a popular choice due to its low breakdown voltage, impressive surge handling capability, and greater than 1500W peak pulse power dissipation. It has an ultra-small size of only 2.6x2.2x1.76mm, making it suitable for many applications where space is limited such as mobile phones and other hand-held devices. The device has a built-in ceramic circuit that ensures fast response times to transient events and provides excellent thermal stability, allowing it to withstand large transient voltages without overheating.

The working principle of SA26CA-B is based on the avalanche breakdown effect. When a high voltage is applied, electrons in the drift region of the diode will gain energy from the electric field, paving the way for avalanche multiplication. This causes a large number of electrons to be emitted into the depletion region, and a large number of holes to be collected from the source. As a result, a very high current is suddenly discharged, resulting in the breakdown voltage being reached and the device becoming forward-biased. The device will continue to conduct until the voltage is no longer above the breakdown voltage or the current is below the holding limit.

The SA26CA-B can be used in a variety of applications that require protection from overvoltage and undervoltage events. It is suitable for use in a wide range of applications including automotive, computing, consumer electronics, industrial, medical, and telecommunications systems. It is also ideal for high-speed protection applications, such as USB ports, LCD displays, and sensors. In addition, the SA26CA-B can be used for ESD protection, short-circuit protection, and other surge protection applications.

The SA26CA-B TVS diode is a reliable and cost-effective solution for protecting against transient voltages and surge currents. It is designed to handle large transient voltages without becoming damaged or failing, and its ultra-small size makes it suitable for use in space-constrained applications. The device offers fast response times, low-breakdown voltage, and impressive surge handling capability, making it suitable for a variety of applications.
