MSDM200-16

Bridge Rectifier Overview

The MSDM200-16 is a glass passivated three-phase rectifier bridge manufactured by Microsemi Corporation. It features a maximum repetitive peak reverse voltage of 1600 V and an average forward rectified current of 200 A per leg. The device utilizes a base-mounted module configuration with isolated terminals for thermal management. Key electrical characteristics include a maximum non-repetitive peak surge current of 3500 A at 8.3 ms single half-sine wave and a maximum DC blocking leakage current of 1 mA at rated voltage. The unit operates within a junction temperature range of -40°C to +150°C.

Bridge Rectifier Feature Summary

• Glass passivation provides environmental protection and stability for the silicon junctions.
• Base-mounted design facilitates efficient heat dissipation through direct mounting to a heatsink.
• Isolated terminal construction allows for safe electrical connection without additional insulators.

Bridge Rectifier Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supply systems
• Inverter circuits in renewable energy applications

Bridge Rectifier Procurement Notes

Verify the specific suffix codes against the official Microsemi datasheet to confirm voltage ratings and pin configurations. Ensure that the procurement channel provides traceability documentation, as this component is often specified for high-reliability industrial environments. Confirm package compatibility with existing thermal management solutions before ordering.

Bridge Rectifier Selection Notes

Select this component when designing three-phase rectification stages requiring high current handling and robust voltage withstand capabilities. Compare the 200 A current rating and 1600 V blocking voltage against system load requirements. Evaluate the thermal resistance characteristics to determine appropriate heatsinking strategies for continuous operation under expected ambient conditions.

Bridge Rectifier Part Context

The MSDM200-16 belongs to the MSD series of glass passivated three-phase rectifier bridges from Microsemi. This series is engineered for demanding power electronics applications where reliability and high current density are critical. It serves as a core component in converting AC input to stable DC output for heavy-duty industrial machinery.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 200 A current rating, 1600 V reverse voltage, and M2-1 or equivalent base-mount package dimensions. Verify that alternative manufacturers offer comparable thermal performance and isolation voltage ratings to ensure circuit integrity without redesigning the mechanical assembly.
