1PMT4123C/TR7 Application Field and Working Principle

The 1PMT4123C/TR7 is a Zener diode, specifically designed to protect electronics’ circuits from overvoltage, and ensure their correct operation in the presence of transient voltage spikes, or extreme levels of noise. It is easy to use, energy efficient and suitable for a wide range of applications from consumer electronics to industrial automation.

Technology

This 1PMT4123C/TR7 Zener diode uses a modern new technology design, which utilizes a tunnel diode structure, low current materials and a higher doping concentration, to achieve its wide operating range. This allows the device to have an exceptionally wide dynamic range, with a low power consumption rate, low noise figure, and a higher breakdown voltage/current than other devices.

Application Field

Due to their low power consumption and extra-wide operating range, 1PMT4123C/TR7 Zener diodes can be used in a wide array of applications, ranging from consumer electronics, such as smartphones or laptops, to industrial applications. In the industrial segment, they are used in industrial automation and production, as protective elements in circuits that could be exposed to transients or overvoltage. Additionally, they can also be used in alternate energy systems, such as solar or wind, as well as in automotive systems.

Working Principle

A Zener diode is an electronic component that is mainly used for voltage regulation. It is able to perform this function because it has a special type of semiconductor junction, where the electrons which are normally blocked from flowing in a reverse direction, can jump through a potential barrier, and start flowing into the device. The special junction of a Zener diode is designed to maintain a consistent voltage at a certain current level, and most of the Zener diodes can both decrease and increase the voltage, depending on the current flow.When in active mode, the Zener diode acts as a rectifier, allowing only one direction for the electric current to flow. However, if the applied voltage is higher than the Zener diode breakdown voltage, the electrons can jump from one side of the junction to the other, and the current will start flowing in both directions at the same time. The voltage at which this phenomenon takes place is known as the Zener voltage, and it is a characteristic of a specific Zener diode. The 1PMT4123C/TR7 has a Zener voltage of 12.3 V.

When a Zener diode is placed in a circuit, it will provide both protection and level shifting functions, allowing a higher voltage to be dropped down to a lower voltage, or vice-versa, depending on the circuit configuration. The 1PMT4123C/TR7 has a relatively low power rating, which makes it suitable for energy-sensitive applications, such as portable electronics and other devices with slow voltage changes.

The 1PMT4123C/TR7 is a general-purpose Zener diode, designed to handle a wide variety of applications and to provide a reliable protection circuit against overvoltage, or voltage spikes. It is easy to use, energy efficient and can be used in a range of settings, from consumer electronics to industrial solutions.
