MBR4050PT-M3/P

Diode Arrays Overview

The MBR4050PT-M3/P is a dual Schottky barrier rectifier from Vishay, configured as a common cathode pair in a TO-3P (SC-65) package. It features a maximum repetitive peak reverse voltage of 50V and an average forward rectified current of 40A per diode. The device utilizes Platinum-class fast recovery technology for low switching losses. Key electrical characteristics include a maximum DC reverse leakage current of 10mA at 50V and a typical forward voltage drop of 0.72V at 20A. It operates within a junction temperature range of -65°C to 150°C.

Diode Arrays Feature Summary

• Platinum-class fast recovery technology ensures minimal switching losses and high efficiency.
• Common cathode configuration simplifies circuit design for dual-rail or bridge applications.
• Low forward voltage drop reduces conduction losses and thermal management requirements.

Diode Arrays Applications

• Switching mode power supplies (SMPS)
• DC/DC converters
• Free-wheeling diodes in inductive load circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific suffix 'M3' confirms lead-free and halogen-free compliance with RoHS standards. Confirm the '/P' designation indicates tube packaging rather than tape and reel. Ensure the TO-3P pinout matches the target PCB footprint, as lead spacing and tab configurations are critical for proper mounting and thermal dissipation in this package style.

Diode Arrays Selection Notes

Select this component when high current handling up to 40A is required alongside a 50V blocking capability. The TO-3P package offers superior thermal performance compared to smaller surface-mount options, making it suitable for high-power density designs. Consider the common cathode arrangement if two separate rectification paths are needed on a single substrate.

Diode Arrays Part Context

This part belongs to Vishay's MBR40 series of high-current Schottky rectifiers. It shares the same physical package and thermal characteristics as variants like the MBR4035PT and MBR4060PT, differing primarily in reverse voltage ratings. The M3 suffix denotes environmental compliance, while the P suffix typically specifies tube packaging for through-hole assembly.

Diode Arrays Replacement Considerations

Compatible substitutes include the MBR4045PT-M3/P (45V rating) and MBR4060PT-M3/P (60V rating), provided the system voltage headroom allows. Direct replacements must maintain the TO-3P form factor and common cathode configuration to ensure mechanical and electrical compatibility without redesigning the PCB layout.
