3EZ18D10E3/TR12

The 3EZ18D10E3/TR12 diode is a commonly used device and part of a family of zener-regulators that offer low-cost and reliable regulation of low-level and medium-power circuits.

This diode is a single-junction, relatively high-power device that has wide variety of applications and is used in many industries. This device is particularly popular in automotive, lighting, communication, and medical industries. It is also used in both military and aerospace sectors.

Application Field

The 3EZ18D10E3/TR12 diode is designed to provide reliable, dedicated over-voltage protection (OVP), and reverse polarity protection. Its high current capacity makes it suitable for regulating medium-power circuits and emergency power supplies. This diode also offers thermal protection, which is especially beneficial for emergency power supplies and for lighting applications, as it helps to prevent overheating and damage to the circuit.

As this diode is thermally protected, it is suitable for circuits that operate in extreme temperatures or environments. It can also be used in applications that involve repetitive switching, such as automotive and industrial applications, as its robust construction and high current capacity allow for long-term reliability.

Other common applications for the 3EZ18D10E3/TR12 diode include LED drivers, LED lighting, power supplies, and power controllers. This diode is also often used in custom-built circuits, such as those used in telecommunications and medical equipment.

Working Principle

The 3EZ18D10E3/TR12 diode integrates a semi-conducting element within an isolated enclosure, creating a p-n junction that limits the current flow when applied to an attached circuit. This junction is known as a Zener barrier, and the current is determined by the forward voltage applied to the p-n junction. The Zener barrier will allow current to flow when the voltage does not exceed a certain threshold—the Zener voltage—which corresponds to the breakdown voltage of the device.

When used in a power-regulating circuit, this diode will regulate the output voltage and prevent it from exceeding the predetermined threshold. This is done by throttling the current flow within the component. This prevents any sudden spikes or fluctuations within the circuit, which could potentially cause damage to sensitive components.

In combination with other components, such as transistors or resistors, the 3EZ18D10E3/TR12 diode can be used as a protection device, limiting the current flow within the circuit and thus protecting it from potential overloads or sudden power surges.

Conclusion

The 3EZ18D10E3/TR12 diode is a high-power, single-junction zener-regulator that is used in a variety of applications, such as automotive, lighting, and communication. This device is thermally protected and offers reliable, dedicated over-voltage protection and reverse polarity protection. In combination with other components, it can be used to regulate current flow and protect against power surges. The high current capacity of this component, as well as its robust construction and temperature protection, make it suitable for use in extreme environments and repetitive switching applications.
