MD165A18D2-BP

Overview

The MD165A18D2-BP is a standard recovery power diode module manufactured by Micro Commercial Components (MCC). It utilizes silicon technology and features a D1 base-mount package. The device is configured as one pair of common cathode diodes. Key electrical specifications include a maximum repetitive reverse voltage of 1800 V and an average rectified forward current of 165 A per diode. The module operates within a junction temperature range of -40°C to +150°C.

Feature Summary

• Standard recovery speed characteristics suitable for general power conversion applications
• Robust silicon construction designed for high-current industrial environments
• Common cathode configuration simplifies circuit layout in bridge or parallel setups

Applications

• Industrial motor drives and variable frequency drives
• High-power DC-DC converters
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix and marking against the official MCC datasheet to ensure authenticity, as counterfeit modules may exhibit incorrect voltage ratings or thermal performance. Confirm RoHS compliance status through the manufacturer's latest environmental declaration, as regulatory requirements vary by region and production batch. Ensure the D1 mounting interface matches your heatsink specifications for proper thermal management.

Selection Notes

Select this module when designing circuits requiring high current handling capabilities exceeding 100 A with high voltage blocking up to 1800 V. The standard recovery time makes it appropriate for lower-frequency switching applications where fast recovery is not critical. Consider the thermal resistance of the D1 package and ensure adequate heatsinking to maintain junction temperatures within the specified -40°C to +150°C operating range during continuous operation.

Part Context

This component belongs to the MD165A18D2 series of discrete semiconductor modules from Micro Commercial Components. The series focuses on high-power silicon rectification solutions for industrial markets. The D1 package provides a standardized mechanical footprint for base-mount installation, facilitating integration into existing power electronics designs that require reliable, high-current diode modules.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative modules by matching the 1800 V reverse voltage, 165 A current rating, and D1 package dimensions. Consult MCC technical support for direct cross-reference recommendations based on specific application requirements.
