Introduction to the 1EZ140DE3/TR8

The 1EZ140DE3/TR8 is an component that belongs to the Single Zener Diodes category. It is a power component that is used to protect electrical circuits from high voltage input as well as regulate the output off a component. The component has a small size and a very low forward voltage drop which makes it ideal for applications where current and space must be conserved.

Application Field and Working Principle

The 1EZ140DE3/TR8 component is primarily used to inhibit voltage surges in both AC and DC circuits. Specifically, it is typically used to protect circuits from transient overvoltage (high-intensity voltage) from a circuit\'s power supply or from a high-intensity AC voltage source. The component is designed to prevent instant destruction of the circuit by withstanding the high-intensity voltage and slowly release the energy to the ground. It will also ensure that the voltage sourced to the load is a stable and acceptable value.The component typically has a low on-state resistance and is able to reverse the current while conducting current. The component has two main working principles: the clamping voltage regulation and the voltage regulation. Clamping voltage regulation occurs when the voltage exceeds the upper limit of the component and the component will start to conduct. This current is then limited to a predetermined value and any further increase in conducted current is blocked. Voltage regulation occurs when the negative electrode of the component is connected to the power supply and the component allows only a predetermined voltage to be sourced to the load.

Features of the 1EZ140DE3/TR8

The 1EZ140DE3/TR8 has a number of features which make it ideal for use in protection circuits. Firstly, it has a termperature coefficient of 0.005V/°C which makes it suitable for use in low temperature environments. Secondly, it has a very low forward voltage drop which is excellent for conserving current usage. Thirdly, it has an operating temperature range of -55°C to +150°C which makes it suitable for use in extreme temperature environments. It also has a power rating of 0.05W to +200W and a reverse breakdown voltage of 12V to 150V.

Conclusion

The 1EZ140DE3/TR8 is a Single Zener Diodes component that is designed for use in protection circuits. It has a number of features including a low temperature coefficient, a low forward voltage drop and an operating temperature range of -55°C to +150°C. The component can be used to inhibit transient overvoltage from sources such as a circuit\'s power supply or from AC voltage sources. The component is also able to regulate the output voltage to a predefined level.
