1PMT4125/TR13 Datasheet/PDFDiodes are an important component of most electronics. The 1PMT4125/TR13 is a type of diode, specifically a Zener diode, designed to function as a voltage regulator. This component helps to maintain a constant voltage despite fluctuations in current and temperature. There are two main types of Zener diodes: single and dual.
Application Field
The 1PMT4125/TR13 is a single Zener diode and is usually used in power supplies and low-voltage regulator circuits. It is used to ensure that the voltage output of a power supply is constant despite changes in current or temperature. It is often used in circuits with a high input/output voltage ratio, where a single Zener diode is sufficient.
The 1PMT4125/TR13 is commonly used in automotive, industrial, and medical applications, as well as in circuit boards in a variety of electronic devices. Its maximum continuous current rating is 1 Amp and its peak pulse current rating is 2.5 Amps. Its maximum reverse voltage is 32 V.
Working Principle
The 1PMT4125/TR13 is a voltage-regulated Zener diode, meaning that it is designed to ensure a constant output voltage regardless of changes in current or temperature. This is done using a mechanism called the Zener Effect. When a reverse voltage is applied to the diode, it will pass a certain amount of current known as the Zener current. This current will cause the diode to become forward biased and will act as a voltage regulator.
In the case of the 1PMT4125/TR13, it will regulate voltage up to a maximum of 32 Volts. This means that when a reverse voltage is applied, the diode will operate as a voltage regulator, maintaining the output voltage despite changes in the input voltage, current, or temperature.
Conclusion
The 1PMT4125/TR13 is a single-type Zener diode designed for power supply and low-voltage regulator circuits. It is used to regulate voltage up to a maximum of 32 Volts, ensuring a constant output voltage despite changes in current or temperature. This makes it a versatile and reliable component for a variety of applications, from automotive and industrial to medical devices.
