MBR4050PT-E3/45

Diode Arrays Overview

The MBR4050PT-E3/45 is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a TO-247AD (TO-3P) case with matte tin-plated leads and RoHS compliance. The device provides a maximum repetitive peak reverse voltage of 50 V and supports a maximum average forward rectified current of 40 A at a case temperature of 125 °C. It includes guardring technology for overvoltage protection, operates up to a junction temperature of 150 °C, and offers high forward surge capability.

Diode Arrays Feature Summary

• Guardring structure designed for enhanced overvoltage protection
• Low forward voltage drop contributing to reduced power losses and high efficiency
• High frequency operation suitable for switching applications
• Matte tin plated leads ensuring solderability per J-STD-002

Diode Arrays Applications

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and delivery mode. Ensure the component meets required environmental standards such as RoHS compliance and material categorization guidelines. Confirm thermal management requirements align with the specified junction-to-case thermal resistance and operating temperature range before finalizing procurement.

Diode Arrays Selection Notes

Select this component for applications requiring a 50 V reverse voltage rating and 40 A continuous current handling in a TO-247AD package. Consider the low forward voltage characteristics for improved efficiency in high-frequency switching environments. Validate that the thermal design accommodates the specified junction temperature limits and surge current capabilities under expected load conditions.

Diode Arrays Part Context

This part belongs to the MBR4035PT through MBR4060PT series of dual common-cathode Schottky rectifiers from Vishay. The series shares identical mechanical dimensions and thermal characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings ranging from 35 V to 60 V. All variants utilize the same TO-247AD case and offer comparable forward current and surge capabilities.

Diode Arrays Replacement Considerations

Direct substitutes within the same Vishay series include MBR4035PT, MBR4045PT, and MBR4060PT, provided the voltage rating matches the application requirements. Verify pinout compatibility and thermal performance when considering alternatives from other manufacturers.
