TVS - Diodes (Transient Voltage Suppressor - Diodes) are semiconductor devices that provide protection against voltage spikes or electrostatic discharge (ESD). They are also known as "surge suppressors" and "ESD clamps". These devices are typically designed to quickly reduce a large voltage spike within a few nanoseconds, depending on the frequency and magnitude of the voltage spike. The 1KSMBJ22CA is a TVS diode, designed to protect sensitive electronics from overvoltage, electrical noise, and ESD.

The 1KSMBJ22CA is most often used in automotive, industrial, medical, and consumer applications that require overvoltage protection. It is a bidirectional device, which means that it can be used in both directions. This device has a breakdown voltage of 22V, which means that it will begin to conduct current if the voltage goes above 22V. Additionally, the 1KSMBJ22CA can operate from -55°C to +175°C, making it a suitable choice for automotive and industrial applications.

The 1KSMBJ22CA’s working principle is simple. When the voltage rises above 22V, the unity-gain voltage regulator opens and begins to conduct current. This reduces the voltage of the spike back to a safe level, protecting the device from damage. The voltage that the device is exposed to is also referred to as the transient voltage, hence the name transient voltage suppressor.

The 1KSMBJ22CA is designed to work efficiently and effectively at high frequencies. The device has a low capacitance of only 0.1pF. This allows it to quickly react to the transient voltage without creating a large amount of noise or heat. Additionally, the device has a low dynamic resistance, which helps protect against ESD.

The 1KSMBJ22CA is a robust and reliable device for protecting against overvoltage, voltage noise, and ESD. It is easy to use and can be used in a variety of applications where protection from overvoltage is needed. The device is fast and efficient, making it a cost-effective solution for protecting sensitive electronics.
