TVS (transient voltage surge suppressor) diodes are semiconductor devices specifically designed to divert surge currents away from sensitive components and have been around since the 1960s, when the first of these devices were commonly known as avalanche type diodes or transzorbers. Modern TVS diodes are typically bidirectional devices, meaning they can operate in either direction by allowing current to flow either way. SMBJ26CA-QH is a popular example of this type of diode.

The SMBJ26CA-QH is a bi-directional transient voltage suppressor diode specifically designed to protect sensitive electronic components from destruction due to an over-voltage condition. It is capable of suppressing transient voltages of up to 26 volts, and has built-in ESD protection for up to 8kV of electrical surge currents. The diode has a peak power rating of 600 Watts for a total clamping of 417V.

The primary application of this TVS diode is to provide protection to sensitive components from high electrical surge currents and voltages. It can be used to protect against both static and dynamic ESD (electro-static discharge) or EFT (electrical fast transients) from lightning strikes, power surges, and so on that may cause malfunction in electronics. The SMBJ26CA-QH is also commonly used in DC/DC converters, monitors, cable modems, telephone lines, and other high power applications.

The working principle behind this type of diode is fairly straightforward. Essentially, when the voltage of an electronic component exceeds a certain predefined threshold, the SMBJ26CA-QH TVS diode will channel the excessive current away from the component, effectively protecting it from the potentially damaging effects of the excess voltage. The diode works by shunting the current from the component in question to a different, more suitable electrical pathway.

The SMBJ26CA-QH is an especially useful device because it is relatively small and lightweight, but still capable of withstanding large surge currents. It also has a low breakdown voltage of 26V, making it well suited for applications that require a high level of protection without taking up a lot of space. It has a high surge handling capability, and is very reliable and consistent in its performance.

Overall, the SMBJ26CA-QH TVS diode is an incredibly useful device for protecting sensitive electronic components from potentially damaging surge currents and voltages. It is easy to install and can be used in a variety of applications to protect electronics from both static and dynamic electrical surges. Offering superior performance and reliability at an affordable price point, this diode is an excellent choice for any electronic device.
