MBRA3045NTU

Diode Arrays Overview

The MBRA3045NTU is a Schottky Barrier Rectifier manufactured by onsemi (formerly Fairchild Semiconductor). It features a dual common cathode configuration housed in a TO-3P package. The device supports an average rectified forward current of 30 A at a case temperature of 130°C and withstands a maximum repetitive reverse voltage of 45 V. Key electrical characteristics include a maximum instantaneous forward voltage of 0.80 V at 30 A and 25°C, and a non-repetitive peak surge current capability of 200 A per diode.

Diode Arrays Feature Summary

• Low forward voltage drop for high efficiency
• Guard ring structure for over-voltage protection
• High frequency properties and fast switching speed

Diode Arrays Applications

• Switched mode power supplies
• Freewheeling diodes
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the specific ordering suffix matches the required lead-free or RoHS compliance status if applicable to your design constraints. Ensure the TO-3P flange mount package dimensions align with your thermal management and mechanical layout requirements.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage drop and high surge current handling capabilities. The TO-3P package provides robust thermal performance suitable for high-power environments. Consider the junction-to-case thermal resistance when designing heat sinks to maintain the junction temperature within the specified operating range under continuous load conditions.

Diode Arrays Part Context

This part belongs to the MBR series of Schottky barrier rectifiers designed for general-purpose high-efficiency rectification. The dual common cathode arrangement allows for use in full-wave rectification or push-pull converter topologies without requiring external wiring complexity. The technology utilizes majority carrier conduction to minimize switching losses.

Diode Arrays Replacement Considerations

Cross-reference with other MBR3045 variants from different manufacturers such as Vishay or Taiwan Semiconductor. Verify pinout compatibility and ensure the replacement device meets or exceeds the 30 A current rating and 45 V reverse voltage specifications while maintaining similar thermal resistance values.
