1EZ130D/TR12 Application Field and Working Principle

1EZ130D/TR12 is a single Zener diode manufactured by STMicroelectronics. It consists of an Oxide-nitride passivated planar diode that provides protection against lightning, overvoltages and other surge protection needs. The 1EZ130D/TR12\'s uniquely designed structure makes it suitable for use in a variety of applications from automotive to consumer electronics. Its components are engineered to handle a wide range of temperatures, from -40 degrees Celsius to 150 degrees Celsius.

The maximum repetitive reverse voltage (VRRM) of 1EZ130D/TR12 is 130 volts, with a static reverse voltage of 100 volts. Its forward leakage current is as low as 4 µA, but it can reach up to 400 µA when at its maximum operating temperature of 150 degrees Celsius. This low leakage current and its temperature limit make it suitable for use in consumer electronics, and applications with high ambient temperatures.

Due to its low leakage current and unique design features, 1EZ130D/TR12 has been used in numerous applications, such as: overvoltage protection, automotive systems, mobile and consumer electronics, and lighting solutions. Its main use is in the protection against surge voltages, as these short and high voltage peaks can easily damage components in other circuits. 1EZ130D/TR12 acts as a “fuse” and will shut off any voltage peak that is higher than its repetitive reverse voltage (VRRM) rating.

Working Principle

The 1EZ130D/TR12 functions as a Zener diode, which regulates the potential difference between input and output by acting as a voltage reference. A Zener diode has two terminals, and when a voltage is applied to it in reverse bias, it will be blocked until the reverse breakdown voltage is reached. This breakdown voltage is known as its Zener voltage, and it is this voltage which the diode acts as a reference. Once the breakdown voltage is reached, electrons flow back into the diode, creating a negative feedback loop and regulating the voltage between input and output.

The 1EZ130D/TR12 also operates as a shunt regulator, which is a device that uses a short circuit in order to maintain a predetermined voltage level. In other words, it is used to maintain constant voltage, despite any changes in the load current or supply voltage. This is achieved by conducting the excess current away from the circuit or back into it, depending on the voltage requirement.

Conclusion

The 1EZ130D/TR12 single Zener diode is an important component for a variety of applications. It is well-suited for use in consumer electronics, automotive systems, mobile devices, and lighting solutions. Its low leakage current and repetitive reverse voltage of 130 volts make it ideal for surge protection and its high temperature limit allows it to perform in hot conditions. It also functions as a Zener diode, providing a voltage reference and regulating the potential difference between input and output, and as a shunt regulator to maintain a constant voltage even when the load current or supply voltage changes.
