MBRF735HE3/45

The MBRF735HE3/45 is an epitaxial-base planar silicon Power rectifier built by the semiconductor manufacturer Vishay Intertechnology. It is designed for general rectification of alternating current in applications with high power dissipation, such as AC-DC power supplies, uninterruptible power supplies, switching mode power supplies and other industrial applications.

Application Field

The MBRF735HE3/45 rectifier is suitable for use in high power switch-mode power supplies and electronic switching applications. It is built to handle full-wave rectification current in both forward and reverse directions, with the capacity to handle up to 735A in peak surge current. The 625V operating voltage makes it suitable for use in both low-voltage and medium-voltage applications.

The rated current of the rectifier is 3.5A and it has a reverse voltage drop at 125°C of 280mV, making it ideal for high-frequency applications where power loss must be kept to a minimum. Its diode recovery time allows for switching transients up to 500kHz, making it suitable for use in modern high-performance electronic systems.

Working Principle

The MBRF735HE3/45 is an epitaxial-base planar silicon power rectifier, meaning it can convert alternating current (AC) into direct current (DC). It works by passing all current in the forward direction, while blocking all current in the reverse direction. This is done by controlling the flow of electrons, allowing current to flow only in one direction and blocking it in the opposite direction.

The MBRF735HE3/45 is built with state-of-the-art planar technology, which allows for a low forward voltage drop and low power loss, making it suitable for high-frequency applications. It uses metal-oxide semiconductor field-effect transistor (MOSFET) technology to control the forward voltage. This allows for a precise control of voltage and current, enabling the rectifier to handle high power surges with minimal power loss.

The robust design and use of cutting-edge technology ensure that the MBRF735HE3/45 is reliable and capable of delivering the highest possible performance during continuous full-wave rectification in various power applications.
