2EZ51D2E3/TR8

Diodes - Zener - Single

The 2EZ51D2E3/TR8 is a single Zener diode made by NXP. It is specifically designed to provide reliable, low cost design approaches to protect signals and components against ESD, transients and overloads. It can also be used as a voltage regulator in applications that require low noise and low input/output impedance.

Applications

The 2EZ51D2E3/TR8 can be used in a wide variety of applications, including:

• ESD and transient protection for sensitive components and circuits
• Providing overvoltage protection for small boards and circuits
• Regulating voltages from 5V to 12V depending on the particular device
• Coupling low-noise circuits with high-voltage circuits
• As a voltage regulator in low-noise, low-impedance applications
• Protecting against output overloads in switching applications

Working Principles

The 2EZ51D2E3/TR8 works by utilizing the Zener principle, which is named after the physicist Dr Clarence Zener, who discovered it in 1928. This principle states that when a reverse-biased P-N junction is under appropriate conditions, it can sustain an electric current even when the voltage exceeds the junction\'s breakdown voltage. This occurs because current begins to flow in the reverse direction in its construction

The 2EZ51D2E3/TR8 is designed to provide reliable overvoltage and ESD protection, at high breakdown voltages and low leakage currents. It is designed to withstand up to an 8kV ESD strike and 5x10^-6 AC leakage current.

It also has a low impedance across its terminals of 0.6K Ohms, meaning that it provides a low-noise, low-ESR design solution, protecting circuits and components from noise, transients and overloads.

Conclusion

In conclusion, the 2EZ51D2E3/TR8 is a single Zener diode generally used to provide reliable, low-cost protection against ESD, transients and overloads. It can also be used as a voltage regulator in applications that require low noise and low input/output impedance. By utilizing the Zener principle, the 2EZ51D2E3/TR8 can provide reliable overvoltage and ESD protection, at high breakdown voltages and low leakage currents.
