MBRF2545CT/45

Diode Arrays Overview

The MBRF2545CT/45 is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the SWITCHMODE Power Rectifier technology, featuring epitaxial construction with oxide passivation and metal overlay contact. The device is housed in an ITO-220AB package, providing electrical isolation without additional hardware. Key electrical ratings include a maximum repetitive peak reverse voltage of 45 V and a total maximum average forward rectified current of 25 A (12.5 A per diode). The component exhibits a low forward voltage drop of 0.73 V at 30 A and supports a peak forward surge current of 150 A.

Diode Arrays Feature Summary

• Guardring structure provides overvoltage protection for enhanced reliability
• Low forward voltage drop contributes to lower power losses and high efficiency
• High junction temperature capability ensures stable operation under thermal stress
• Epoxy meets UL 94 V-0 flammability rating for safety compliance

Diode Arrays Applications

• Low voltage, high frequency rectification in switching mode power supplies
• Freewheeling diodes in DC/DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and compliance status. The datasheet indicates that base part numbers ending in -E3 denote RoHS-compliant commercial grade components with matte tin plated leads. Confirm the required delivery mode, such as tube quantities, matches the procurement specifications before finalizing orders.

Diode Arrays Selection Notes

Select this component when designing circuits requiring isolated dual Schottky rectification in an ITO-220AB form factor. The 45 V reverse voltage rating suits low-voltage applications, while the 150 A surge capability handles transient loads. Ensure thermal management accounts for the higher thermal resistance characteristic of the ITO-220AB package compared to standard TO-220AB variants.

Diode Arrays Part Context

This device belongs to the MBR25xxCT family of dual common cathode Schottky rectifiers from Vishay. The MBRF2545CT variant specifically denotes the ITO-220AB plastic package configuration, which offers electrical isolation between the terminals and the heatsink mounting surface. This distinguishes it from the non-isolated MBR2545CT version housed in a standard TO-220AB case.

Diode Arrays Replacement Considerations

Direct replacements within the same Vishay series include the MBR2535CT/45, which shares identical package and current ratings but features a reduced 35 V reverse voltage rating. Verify that the lower voltage threshold of the substitute part remains sufficient for the target application's peak reverse working voltage requirements.
