MBR3045WT

Diode Arrays Overview

The Vishay MBR3045WT is a dual common cathode Schottky rectifier in a center tap TO-247AC package. It features two independent anodes sharing a common cathode, rated for a maximum average forward current of 15 A per leg (30 A total) and a peak repetitive reverse voltage of 45 V. The device operates with a junction temperature range from -65 °C to +150 °C. Electrical characteristics include a maximum forward voltage drop of 0.76 V at 30 A and 25 °C, and a non-repetitive peak surge current capability of 1020 A.

• Center tap configuration with dual anodes and a common cathode
• Guard ring structure designed for enhanced ruggedness and long-term reliability
• Proprietary barrier technology enabling reliable operation up to 150 °C junction temperature
• High purity, high temperature epoxy encapsulation providing mechanical strength and moisture resistance

Diode Arrays Applications

• Switching power supplies
• DC-to-DC converters
• Freewheeling diodes
• Reverse battery protection circuits

Diode Arrays Procurement Notes

Verify the specific part number suffix against official Vishay documentation to confirm lead-free status and packaging details. Ensure that the thermal management design accounts for the specified thermal resistance values to maintain safe operating temperatures within the 150 °C limit during continuous operation.

Diode Arrays Selection Notes

Select this component when a dual Schottky rectifier with a center tap configuration is required for low forward voltage drop applications. Consider the TO-247AC package for through-hole mounting and verify that the 45 V reverse voltage rating meets the circuit's peak repetitive reverse voltage requirements.

Diode Arrays Part Context

This component belongs to the Vishay MBR series of high-power Schottky rectifiers. It shares the same physical package and general electrical architecture as the MBR3035WT, differing primarily in the maximum DC reverse voltage rating. Both devices utilize the same proprietary barrier technology and are optimized for high-frequency operation in industrial environments.

Diode Arrays Replacement Considerations

The MBR3035WT serves as a direct functional substitute within the same Vishay family, offering identical current ratings and package dimensions but with a lower 35 V reverse voltage rating. Verify that the reduced voltage rating does not compromise the safety margin in the target application.
