NRVHP140SFT3G

Diodes are a type of electrical component that allows current to flow in only one direction. This basic principle has a wide range of applications, from controlling current flow in electronics, to switch mode power supplies, and even as light emitting diodes (LEDs). The NRVHP140SFT3G is an example of a single rectifier diode for use in a wide variety of applications.

Overview

The NRVHP140SFT3G is a single rectifier diode with a breakdown voltage of 140V. It has an operating temperature range of -55°C to +125°C and a reverse leakage current of 75uA at 25°C. The diode has an indirect solder pin configuration and is rated up to 3.3A with a thermal junction temperature of +150°C.

Application Fields

The NRVHP140SFT3G is particularly well suited for applications in automotive, communications, consumer electronics, commercial lighting, and power supply systems. It is an optimal choice for applications with high current switching and low-to-medium voltage reverse protection. The rectifier diode can be used in a variety of applications, from AC/DC converters to switched-mode power supplies and DC/DC converters.

Working Principle

The basic operation of any diode is to allow current to flow in one direction only. The principle applies to the NRVHP140SFT3G as well; when the applied voltage is forward biased, the diode turns on and the current flows through the diode. When the applied voltage is reversed the diode turns off and no current flows. This principle can be applied to create various types of rectifying circuits, such as full wave rectifiers or bridge rectifiers.

Full-wave rectification is the most commonly used rectification method, and consists of a series of two diodes connected together to allow current to flow in both directions. The two diodes alternate in their forward-biased flow of current, thus creating a regular alternating current waveform that is converted into a direct current flow. This rectified current can then be directed to a load or voltage regulator to provide DC power.

Bridge rectification is another commonly used rectifying circuit. This circuit consists of four diodes connected in a bridge pattern, with each diode only allowing current to flow in one direction. The input AC waveform is directed through this bridge circuit and the current is then completely rectified, exceeding the single diode rectification efficiency.

Conclusion

The NRVHP140SFT3G is a single rectifier diode that can be used in a variety of applications, from automotive electronics to switched-mode power supplies. Its breakdown voltage of 140V and operating temperature range of -55°C to +125°C make it an ideal choice for use in these areas. Its reverse leakage current of 75uA also helps to keep power usage to a minimum.

By understanding the principles of operation of a diode, such as forward-biased and reversed voltage, engineers can use the NRVHP140SFT3G to create rectifying circuits, such as those found in full-wave and bridge rectifiers. As an industry-standard diode, this rectifier provides reliable performance, is cost-efficient, and can be used to effectively manipulate electric current in a variety of applications.
