TVS diodes are devices that protect electronic circuits from transient events such as electrostatic discharge, voltage surges, and over-voltage conditions. They are widely used in a variety of applications and are available in many different package sizes. The SMB8J26CHE3/5B is one of these packages and is designed to protect both low- and high-voltage circuits from transients. In this article, we will discuss the application fields and working principles of the SMB8J26CHE3/5B.

The SMB8J26CHE3/5B is a low capacitance, low power unidirectional TVS diode. It is designed to clamp single-wires, differential-line pairs, and cables connected to sensitive electronics. It is a two-pin package with a solderable terminal design. The device has a low capacitance of 0.6pF and a breakdown voltage (VBR) ranging from 8V to 26V. It is a high-speed device with an ultra-fast response time of 8ns. The SMB8J26CHE3/5B also has an excellent temperature stability, allowing it to operate over a wide temperature range.

The SMB8J26CHE3/5B has a variety of application fields, including consumer electronics, automotive systems, industrial control systems, power supply systems, and telecommunications systems. It can protect sensitive electronics from voltage transients, ESD, lightning surges, and other over-voltage conditions. It can also protect a variety of communication interfaces, including CANbus, Ethernet, and USB. Additionally, it can be used as a protection element within high-power on/off switches, relays, and solenoids.

The working principle of the SMB8J26CHE3/5B is quite simple. When a transient event occurs, an excess voltage builds up on its terminals. The device responds to this excess voltage by conducting charge carriers across its junction. This conduction increases the current flow between its terminals, resulting in the dissipation of the excess voltage. The device then recovers after the transient event has passed.

In conclusion, the SMB8J26CHE3/5B is a robust and reliable TVS diode that can be used in a variety of applications to protect sensitive circuits from transient events. With its low power usage and fast response time, it can effectively protect vulnerable circuits from damage. This makes the SMB8J26CHE3/5B a great choice for a wide range of applications.
