Diodes are electronic components capable of conducting an electric current in one direction while blocking flow of current in the opposite direction. Single Zener diodes, such as 3EZ5.6D2E3/TR12, are particularly useful for regulating voltage in a circuit. Such diodes are able to convert AC power to DC power, provide protection against overvoltage, and ensure that voltage in a circuit does not exceed a safe threshold. The 3EZ5.6D2E3/TR12 single Zener diode, for example, is commonly used in communication, automotive, and battery-operated applications.

Zener diodes receive their name from the physicist Clarence Zener, who demonstrated in 1934 that a diode can be used to ‘break down’ or allow current flow in either direction when a certain threshold voltage is applied. This behavior is known as the Zener effect, and explains the usefulness of single Zener diodes in applications requiring voltage regulation. When a single Zener diode features a reverse bias voltage equal or higher to the Zener voltage, current will flow through the diode in both directions, allowing the diode to regulate the voltage in the circuit.

To use a single Zener diode in a circuit, reverse voltage must be applied to the diode. This means applying a negative charge to the anode of the diode, rather than a positive one, as is the case with a standard diode. Once reverse voltage reaches the Zener voltage threshold, current is able to flow from the anode to the cathode. For the 3EZ5.6D2E3/TR12 single Zener diode, this Zener voltage ranges between 5.2 V and 6.7 V, depending on the current applied. When the voltage is below the Zener voltage, the diode will prevent current flow, similar to the behavior of a standard diode.

The Zener voltage of a single Zener diode is easily determined by measuring the voltage across it when the diode is in reverse bias and a known current is flowing. The 3EZ5.6D2E3/TR12 single Zener diode has an average max forward current of 200 mA. This is sufficient for most voltage regulation applications, and largely explains why this diode is used in so many applications. It is also an ideal diode for applications requiring low noise and low power consumption, as it has low forward voltage drop and low leakage current.

In summary, single Zener diodes, such as the 3EZ5.6D2E3/TR12, are useful for regulating voltage in a circuit. Such a diode, when connected in reverse bias, will allow current to flow through it when a certain, predetermined threshold voltage is reached. Such a diode is particularly useful for applications requiring low noise, low power consumption, and the ability to convert AC power to DC power. Therefore, single Zener diodes, such as the 3EZ5.6D2E3/TR12, are frequently used in various communication, automotive, and battery-operated applications.
