MBR4045PT

Diode Arrays Overview

The MBR4045PT is a discontinued Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single-phase, half-wave configuration with two elements in a common cathode arrangement. The device is housed in a TO-3P plastic case and rated for a maximum repetitive reverse voltage of 45V. It supports an average rectified output current of 40A at a case temperature of 125°C. Key electrical characteristics include a forward voltage drop of 0.80V at 20A and 25°C, and a peak non-repetitive forward surge current capability of 400A. The component operates within a junction and storage temperature range of -65°C to +150°C.

Diode Arrays Procurement Notes

This part number is officially marked as obsolete and discontinued by the manufacturer. Sourcing new original units from authorized distribution channels is not possible. Verification of authenticity is critical when evaluating surplus or secondary market stock. Designers should prioritize engineering change orders to replace this component with active equivalents to ensure long-term supply chain stability and manufacturing continuity.

Diode Arrays Selection Notes

Selection requires careful consideration of the device's obsolete status. Engineers must evaluate alternative components that match the 40A current rating and 45V reverse voltage specifications. Compatibility checks should focus on thermal resistance, package dimensions, and forward voltage characteristics to ensure seamless integration into existing circuit designs without requiring significant layout modifications.

Diode Arrays Part Context

The MBR4045PT belongs to the MBR4030PT through MBR4060PT series of 40A Schottky barrier rectifiers. This family shares identical mechanical packaging and general performance profiles, differentiated primarily by their peak repetitive reverse voltage ratings which range from 30V to 60V. The series utilizes silicon technology optimized for high-efficiency rectification in power conversion systems.

Diode Arrays Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must identify cross-compatible devices based on specific electrical parameters and physical footprint requirements.
