MSDM150-16

Bridge Rectifier Overview

The MSDM150-16 is a glass-passivated three-phase full-wave rectifier bridge manufactured by Microsemi Corporation. It features a maximum repetitive reverse voltage (VRRM) of 1600 V and a surge peak repetitive reverse voltage (VRSM) of 1700 V. The module supports an average forward current (ID) of 150 A at a case temperature of 100°C, with a non-repetitive peak forward surge current (IFSM) of 1800 A for 10 ms. Electrical characteristics include a typical forward voltage drop of 1.40 V at 150 A and a maximum reverse leakage current of 6 mA at 150°C. Thermal resistance from junction to case is 0.65 °C/W per diode. The component utilizes an M3-1 package with a ceramic isolated metal baseplate.

Bridge Rectifier Procurement Notes

Verify the specific part number suffix against official documentation to confirm exact electrical ratings and physical dimensions. Confirm RoHS compliance status as manufacturing specifications may vary by production batch. Ensure thermal interface materials are compatible with the M3-1 package mounting requirements. Validate that the selected component meets the required isolation voltage standards for the intended application environment.

Bridge Rectifier Selection Notes

Select this component based on the 1600 V blocking voltage requirement and 150 A continuous current capacity. Consider the thermal resistance values when designing the heatsink system to maintain junction temperatures within the specified -40°C to +150°C range. Evaluate the mechanical mounting torque specifications for both terminals and heatsink connections to ensure secure installation and optimal heat dissipation performance.

Bridge Rectifier Part Context

The MSDM150 series includes variants with different voltage ratings: MSDM150-08 (800 V), MSDM150-12 (1200 V), MSDM150-16 (1600 V), and MSDM150-18 (1800 V). All variants share the same 150 A current rating and M3-1 package outline. The series is designed for high-power industrial applications requiring robust three-phase rectification capabilities.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 1600 V rating, 150 A current capacity, and M3-1 package dimensions. Verify equivalent thermal resistance and isolation voltage specifications. Cross-reference UL approval numbers if regulatory compliance is required for the end product.
