MBR2545CT-E3/4W

Diode Arrays Overview

The MBR2545CT-E3/4W is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the TO-220AB package and features Guardring technology for overvoltage protection. The device supports a maximum repetitive peak reverse voltage of 45 V and provides a total maximum average forward rectified current of 25 A, with 12.5 A per diode at a case temperature of 130 °C. It exhibits a typical thermal resistance from junction to case of 1.5 °C/W per diode and operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Feature Summary

• Guardring structure provides enhanced overvoltage protection capabilities
• Low forward voltage drop contributes to high efficiency and lower power losses
• High forward surge capability ensures robustness against transient currents
• Suitable for high frequency operation in switching applications

Diode Arrays Applications

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

Diode Arrays Procurement Notes

Verify the specific ordering suffix '4W' against the manufacturer's official documentation to confirm packaging details and delivery mode. Ensure that the component meets RoHS compliance requirements as indicated by the 'E3' designation. Confirm availability status directly with authorized distributors or the manufacturer, as production lifecycles may change without notice.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for low voltage rectification. The TO-220AB package facilitates through-hole mounting and heatsinking. Consider the 45 V reverse voltage rating and 12.5 A per diode current capacity relative to the specific circuit load requirements. Evaluate the thermal management needs based on the specified junction-to-case thermal resistance.

Diode Arrays Part Context

This part belongs to the MBR25xxCT series of dual common cathode Schottky rectifiers from Vishay. The series includes variants with different reverse voltage ratings, such as the MBR2535CT (35 V) and MBR2545CT (45 V). The 'E3' suffix denotes RoHS compliance and matte tin plating, while the '4W' suffix specifies the tube packaging format for the TO-220AB case.

Diode Arrays Replacement Considerations

Compatible substitutes include the MBR2545CT-E3/45 from Vishay, which shares identical electrical characteristics and package type but uses a standard tube packaging code.
