SMB8J26C-E3/5B

TVS-Diodes are used to protect sensitive electronic components from transient over-voltage events, such as electrostatic discharge (ESD) and power surges. The SMB8J26C-E3/5B is a diode module designed specifically to protect Equipment connected to a communication line. It combines the base of a rectifier diode with a Zener diode to provide a clamping voltage, thus protecting the equipment from over-voltage or over-current.

The SMB8J26C-E3/5B module consists of two silicon Zener-diode elements in series to achieve a symmetrical breakdown voltage of 26 volts at 6A. The E3 model includes an ignition element to support current handling capabilities of up to 18A for a short duration without damage. The E5 model includes an ignition element that supports current handling capabilities of up to 30A for a short duration without damage.

The SMB8J26C-E3/5B module is typically used for protecting the cable to prevent damage from ESD, surge, and static electricity. It can be used in communications and power systems, as well as in computer, media, and consumer electronics. It is especially suited for applications where data is transmitted over a long distance.

The working principle of the SMB8J26C-E3/5B module is based on the Zener diode effect. When the input voltage exceeds the Zener voltage, the diode will conduct a current and act as a passive low impedance shunt. This will effectively limit the voltage across the protected component to the Zener voltage, thus protecting it from any possible over-voltage or over-current. The diode can also help to suppress common-mode EMI noise.

The SMB8J26C-E3/5B module is a reliable over-voltage protection device that provides quick and effective protection against ESD, surge, static electricity, and other transient overvoltage events. It is rated for operation up to 125°C and is suitable for use in harsh environments. The E3 and E5 models have enhanced surge capability enabling them to handle more current. The diode is easy to install and can be configured for use with various communication systems.

In conclusion, the SMB8J26C-E3/5B module is a reliable device designed to provide effective protection from transient over-voltage events. It is used mainly in communications and power systems, as well as in other electronics applications. It is highly efficient and can help to reduce downtime caused by ESD, surges, and similar overvoltage events. The E3 and E5 models offer enhanced surge capability and are especially designed for use in harsher environments.
