Overview
The MD70A08D1-BP is a silicon-based standard recovery power diode module manufactured by Micro Commercial Components. It features a dual-common anode configuration housed in the D1 screw-mount package. The device supports a maximum repetitive peak reverse voltage of 800 V and a continuous forward current of 70 A per leg. It exhibits a typical forward voltage drop of 1.2 V at rated conditions. The module operates within a junction temperature range of -40°C to +150°C, ensuring reliability in high-power industrial applications.
Feature Summary
- Dual-common anode topology for efficient bridge rectification
- High thermal stability with extended operating temperature range
- Robust screw-mount construction for secure mechanical attachment
Applications
- Industrial motor drives and variable frequency drives
- High-power DC power supply rectification
- Inverter and converter circuits in renewable energy systems
Procurement Notes
Verify the specific suffix BP against the manufacturer's latest datasheet to confirm pinout compatibility and packaging details. Confirm RoHS compliance status directly with the supplier documentation prior to integration. Ensure that the D1 package dimensions match the intended heatsink interface requirements for proper thermal management during assembly.
Selection Notes
Select this component when a dual-common anode configuration is required for three-phase or full-bridge rectification topologies. The 70 A current rating and 800 V blocking voltage make it suitable for medium-voltage industrial power conversion. Evaluate the thermal resistance characteristics against the system's cooling capabilities to ensure junction temperatures remain within the specified operational limits under continuous load.
Part Context
This part belongs to the MD70A series of discrete semiconductor modules from Micro Commercial Components. The series includes variants with different voltage ratings, such as the MD70A16D1-BP which offers a higher 1.6 kV rating. These modules are designed for high-reliability power electronics applications requiring robust silicon diode performance in standardized packages.
Replacement Considerations
The MD70A16D1-BP is a confirmed substitute within the same family offering identical physical dimensions and pinout but with a higher 1.6 kV voltage rating. Verify that the increased voltage rating does not impact switching characteristics required by the specific circuit design.
