The 1PMT4114C/TR7 is a zener diode, otherwise known as a voltage reference diode, which provides a stable reference voltage. It is a single diode that is typically used within a variety of applications such as voltage regulation, wave shaping, voltage clamping, noise reduction, and overvoltage protection. This device is specifically designed to meet industrial-level automotive requirements and the characteristic impedance of the diode is approximately equivalent to that of other components in the circuit.

The 1PMT4114C/TR7 is a reverse-biased, planar zener diode which has a breakdown voltage of 5.2V. It has a power dissipation of 500mW, a junction capacitance of 14pF, a reverse leakage current of 10μA, and an operating temperature range of -55 to +150°C. The device is encapsulated in a 4-pin package for ease of installation and handling. Moreover, the diode has a low power loss and capacitance due to its high-quality construction, which enhances its overall performance.

The working principle of the 1PMT4114C/TR7 is fairly straightforward. When the terminal voltage is below the breakdown voltage, the device appears as an open circuit and no current will flow through it. However, when the voltage exceeds the breakdown voltage, a large current surge occurs, which is known as zener breakdown. During this process, a great amount of energy is created, resulting in a drop in voltage and limiting the current. This phenomenon helps eliminate current jumps that would otherwise occur if the circuit were not properly regulated.

This diode is typically used in voltage-regulated power supplies, voltage clamping circuits, wave shaping circuits, power protection for battery-powered applications, and noise reduction. The 1PMT4114C/TR7 can also be used in automotive applications, particularly in automotive powertrains and electric control units, where its low capacitance, low power loss and tight tolerance make it an ideal choice. Additionally, it can be used in sensing and monitoring systems in various vehicles.
