2EZ27D5-TP is a single zener diode made by ON Semiconductor, a global leader in providing semiconductor solutions for applications that require high performance and quality, long term supply and support.

Application Field

The 2EZ27D5-TP is primarily used for voltage regulator, reverse biasing and transient protection applications. It allows current to flow in one direction while blocking it in the other.

2EZ27D5-TP is often used as a voltage reference, as part of a voltage regulator circuit or as a protected switch, preventing any voltages greater than the zener voltage from being applied to the circuit.

It also finds its application in voltage transients protection circuits, where it absorbs any surges or spikes that occur due to a direct or indirect lightning strike.

In most cases, 2EZ27D5-TP is used with an external resistor, to limit the amount of current flowing through it. The selection of the resistor should be based on the value of the zener diode and the total power to be dissipated.

Working principle

2EZ27D5-TP is a Zener diode, which is a type of semiconductor that allows current to flow in one direction, but not the other. This allows it to be used as a voltage reference and to provide protection against voltage surges.

Unlike normal diodes, the 2EZ27D5-TP can withstand voltages greater than its rated voltage, without breaking down. This is because the electric field in the Zener diode is asymmetric, allowing it to withstand higher voltages without degradation.

The voltage breakdown of a Zener diode depends on the doping level of the material and the operating temperature. This allows for precise regulation of the output voltage.

For protection applications, the Zener diode can be connected in a reverse bias configuration, i.e. with the anode connected to the positive supply and the cathode connected to the ground. This will allow it to absorb the energy of any voltage surges, before they reach the load.

The 2EZ27D5-TP can also be used with an external resistor, to limit the current flowing through it. This helps to dissipate the energy of any surges, as well as maintaining the output voltage.

The 2EZ27D5-TP is a versatile diode and can be used in a variety of applications, depending on the required operating conditions. It is an ideal choice for voltage regulator, reverse biasing or transient protection circuits.
