MCD72-18IO1B

Overview

The IXYS MCD72-18IO1B is a discrete semiconductor module belonging to the MCD series, designed for high-power phase leg applications. It utilizes silicon technology and features a screw mount installation style within a TO-240AA package. The device supports a maximum repetitive reverse voltage of 1800 V and delivers an output current of 72 A. Key electrical parameters include a forward voltage of 1.1 V, a gate trigger current of 150 mA, and a maximum holding current of 200 mA. The operational temperature range spans from -40 C to +100 C.

Feature Summary

• High-voltage capability suitable for demanding power conversion environments
• Robust silicon construction ensuring reliable performance under thermal stress
• Standardized TO-240AA packaging facilitating straightforward integration into existing thermal management systems

Applications

• Industrial motor drives requiring robust phase leg components
• Uninterruptible power supply (UPS) systems
• High-frequency power supplies and inverters

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm any distinct manufacturing revisions or testing criteria compared to standard variants. Ensure compatibility with existing thermal interface materials and mounting hardware specifications before finalizing procurement orders.

Selection Notes

Select this component when a 72 A continuous current rating at 1800 V blocking voltage is required in a compact form factor. Evaluate thermal resistance requirements carefully, as the TO-240AA package necessitates adequate heatsinking to maintain junction temperatures within the specified operating limits during peak load conditions.

Part Context

This module is part of the broader IXYS MCD family, which encompasses various thyristor and diode configurations. It shares design principles with other models like the MCD95-16IO8B and MCD162-16IO1, offering consistent mounting standards and electrical characteristics across different current and voltage ratings within the product line.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Consider equivalent modules from the same manufacturer with matching voltage and current ratings, such as the MCD72-18IO1, while verifying pinout and thermal interface compatibility.
