Diodes - Zener - Single

A Zener diode is a type of diode that, unlike a normal diode, allows current to flow in both directions. This unique property makes it ideal for applications that require a variable voltage or current, such as voltage regulators or current limiters. The 1N5347E3/TR8 is a single Zener diode with a maximum current of 1.5A and a breakdown voltage of 3.3V. Application Field

1N5347E3/TR8 Zener diodes are designed for use in voltage regulation and current limiting applications. They are commonly used in power supplies, voltage regulators, and amplifiers. Some of their possible applications include:• Regulating AC line voltage to allow an automated device to run without interference • Powering a circuit that requires a stable voltage level • Providing a path to ground for electronic signals • Protecting sensitive components from high voltage transients • Limiting the maximum voltage of high voltage circuits Working Principle

A Zener diode is a diode that is specifically designed to operate in the breakdown region of its characteristic curve. When the voltage across the diode reaches a certain point known as the "Zener voltage," the diode begins to conduct in the reverse direction. This allows current to flow from an higher-voltage source and be limited to the Zener voltage. In the case of the 1N5347E3/TR8, the Zener voltage is 3.3V and the maximum current is 1.5A. When the 1N5347E3/TR8 is connected in series with a power source, current will flow through the diode until the voltage across it reaches 3.3V. Once this point is reached, the diode will start to conduct in the reverse direction and limit the voltage to 3.3V. This allows electronic circuits to be powered with a stable and consistent voltage. In addition, the 1N5347E3/TR8 can be used as a current limiter by connecting it in parallel with the power source. This will limit the maximum current to 1.5A and protect the circuit from over-currents. Conclusion

The 1N5347E3/TR8 is a single Zener diode that is designed for use in voltage regulation and current limiting applications. It has a Zener voltage of 3.3V and a maximum current of 1.5A. It can be used to regulate AC line voltages, protect sensitive components from high voltage transients, and provide a path to ground for signals. It can also be used as a current limiter by connecting it in parallel with the power source.
