TVS (Transient Voltage Suppressor) diodes are semiconductor devices specially designed to protect sensitive electronic circuits against transient voltage surges or spikes. The SMBJ26CA-TP series of devices belong to this category, and they are most widely used in telecommunications, computing, automotive and consumer electronics applications.

For instance, the SMBJ26CA-TP can be used in data lines of digital interconnects, such as HDMI, UART, Ethernet, and trunk cables. It is also suitable for use in consumer electronics for protection of AC/DC adapter ports of laptops, and displays. It is also used in automotive systems, to protect against surges caused by automotive ignition noise.

The SMBJ26CA-TP devices are specifically designed to protect against high voltage transients and to handle extremely short rise and fall times. They have a fast response time of less than 1ns, and a maximum clamping voltage of 26 volts. This makes them highly suitable for high-speed digital communication systems.

The working principle of TVS diodes is that they act as a voltage limiter when the input voltage exceeds a certain threshold. This is done by allowing the excess voltage to bypass the diode and divert it to ground, thereby limiting the voltage to a certain level. The SMBJ26CA-TP series device has a breakdown voltage of 26 volts, meaning that it can effectively handle input voltages up to this level.

The SMBJ26CA-TP series is also designed to be highly reliable, proven by its UL Flammability Classification rating of 94V-0. This means that it provides excellent protection against the effects of current and voltage surges, and is well suited for applications in which the risk of fire is high. Furthermore, it is also resistant to reverse bias and electrostatic discharge, making it an ideal choice for protecting sensitive electronic components.

To summarize, the SMBJ26CA-TP series of TVS diodes are most suitable for protection of sensitive electronic components from voltage and current surges. They have a fast response time and a high breakdown voltage of 26volts, which makes them highly reliable and suitable for a variety of applications, such as in AC/DC adapters, consumer electronics, automotive systems, and digital communication systems.
