Diodes are an important part of semiconductor devices, used to control the current flow in various electronic circuits. A single-diode, also referred to as a rectifier, is one of the most basic types of electronic devices, consisting of a single semiconductor material along with two electrodes, one anode and one cathode. The MBRF735-E3/45 is a single diode suitable for various circuit applications. This article will discuss the application fields, working principle and features of the MBRF735-E3/45.

Application Fields

The MBRF735-E3/45 single diode is designed for rectification and voltage-clamping applications in consumer, industrial, and automotive circuits. It is widely used in automotive applications, such as ECU, central locking, immobilizer, lighting, and power management due to its high rated current and low reverse leakage current. The MBRF735-E3/45 is also ideal for lighting applications, where the frequency range is from 40Hz to 400kHz and power factor is from 0.5 to 0.9. In consumer and industrial circuits, the MBRF735-E3/45 is suitable for power supplies, motor control, and other electronic circuits.

Working Principle

A single diode or rectifier works by allowing current (in the form of electrons) to flow in one direction while prevent current from flowing in the opposite direction. This means that when a positive potential is applied to the anode of the diode, electrons will flow from the anode to the cathode and power the circuit, while when a reverse potential is applied, the diode will block the current and the circuit will remain unpowered. This process is known as rectification.

The MBRF735-E3/45 single diode is designed to allow the current to flow only in the forward direction, with a forward voltage drop of about 0.7V. The minimum reverse breakdown voltage of the diode is 300V, and the maximum reverse leakage current is 10nA, resulting in efficient rectification with low conduction losses.

Features

The MBRF735-E3/45 single diode features a wide operating temperature range of -40°C to +85°C and a high maximum forward current of 3.45A. It is designed with a flat surface-mountable package that enables efficient thermal dissipation of heat and improved mechanical strength. The diode features an integrated mounted heat-dissipation device that helps to reduce thermal stress and improve the overall system reliability. Additionally, the MBRF735-E3/45 single diode is designed with Superior Avalanche energy withstanding capability, ensuring safe operation even in extreme temperature fluctuations.

The MBRF735-E3/45 single diode is an efficient, reliable and cost-effective solution for various rectification and voltage-clamping applications. Its wide operating temperature range, high maximum forward current and low reverse leakage current make it well-suited for a variety of automotive, industrial and consumer circuits.
