MD250S16M3-BP

Bridge Rectifier Overview

The MD250S16M3-BP is a glass passivated three-phase rectifier bridge manufactured by Micro Commercial Components. It features an M3 chassis mount package and supports a maximum repetitive peak reverse voltage of 1600V with a forward current rating of 250A at a case temperature of 100°C. The device exhibits a maximum forward voltage drop of 1.60V at 300A and a non-repetitive surge current capacity of 2500A for 10ms. Thermal resistance from junction to case is 0.36°C/W per diode, while the junction-to-heatsink resistance is approximately 0.02°C/W. Operating temperatures range from -40°C to +150°C.

Bridge Rectifier Feature Summary

• Utilizes glass passivation technology for enhanced reliability and protection against environmental stressors.
• Incorporates heat transfer through an aluminum oxide DBC ceramic isolated metal baseplate for efficient thermal management.
• Designed for robust chassis mounting using standardized screw terminals.

Bridge Rectifier Applications

• Three-phase rectifiers for industrial power supplies
• Rectifiers for DC motor field supplies
• Input rectifiers for variable frequency drives

Bridge Rectifier Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm RoHS compliance via the BP suffix designation. Ensure proper handling and storage conditions are maintained according to manufacturer standards to preserve component integrity prior to assembly.

Bridge Rectifier Selection Notes

Select this component when a high-current three-phase rectification solution is required with a 1600V blocking voltage capability. Consider the M3 package dimensions and chassis mounting requirements during mechanical design. Evaluate thermal management needs based on the specified junction-to-case thermal resistance and derating curves for continuous operation.

Bridge Rectifier Part Context

This part belongs to the MD250SxxM3 series, which includes variants with different voltage ratings such as 800V, 1200V, 1800V, and 2000V. All members share the same 250A current rating and M3 package form factor, allowing for modular design flexibility within power conversion systems requiring similar current handling capabilities.

Bridge Rectifier Replacement Considerations

Direct substitutes include other MD250S16M3 variants from the same series if voltage ratings differ slightly. Cross-compatibility with other manufacturers' three-phase bridges requires verification of pinout configurations, mounting hole patterns, and thermal interface specifications to ensure mechanical and electrical equivalence.
