Diodes - Zener - Single

The 2EZ56D/TR8 diode is a single Zener diode, a type of diode which is specifically designed to allow current to flow in a single direction but also to act as a voltage regulator. This is achieved by creating a non-linear junction between one side of the diode and the other. This junction, which is referred to as a Zener junction, allows the diode to break down and regulate voltage even when it is under heavy load. This is what makes the 2EZ56D/TR8 diode a popular choice for applications involving power regulation.

Application Field

The 2EZ56D/TR8 diode is ideal for applications that require a regulated voltage output when the input voltage exceeds a certain level. It is especially useful for applications such as DC-DC boost converters, positive voltage regulators and buck converters. The 2EZ56D/TR8 diode is also popular as a replacement for zener diodes in circuits where higher power ratings and/or breakdown voltages are required. This diode is also commonly used in audio circuits and in communications systems where voltage regulation is needed to ensure that signal integrity is maintained.

Working Principle

The 2EZ56D/TR8 diode works on the process of avalanche breakdown, which occurs when the electric field goes beyond the critical field level of the junction. At this point, the diode begins to breakdown and allows a current to flow. The voltage across the junction is essentially fixed, as the forward voltage drop is only determined by the saturation current. This allows the diode to act as a voltage regulator, with the breakdown voltage essentially acting as a limiting factor for the output voltage. The breakdown voltage of the 2EZ56D/TR8 diode is usually within a range of 3.2 to 7.2 volts.

The 2EZ56D/TR8 diode has a power rating of 1.5W and a tolerance of ± 5%. This means that it is suitable for use in a number of high power applications. The diode also has a maximum reverse voltage of 7.2V, meaning that it can be used as a replacement for zener diodes in circuits where a higher breakdown voltage is required. The low forward voltage drop of the 2EZ56D/TR8 diode also makes it an excellent choice for applications such as DC-DC boost converters, positive voltage regulators and buck converters, as the low VF ensures efficient operation with minimum power losses.
