CM100DU-34KA

Overview

The CM100DU-34KA is a Powerex IGBTMOD™ half-bridge module designed for high-power switching applications. It features a collector-emitter breakdown voltage of 1700 V and a continuous collector current rating of 100 A. The module supports a maximum power dissipation of 890 W, enabling efficient thermal management in demanding environments. With an operating junction temperature range of -40°C to 150°C, it ensures reliable performance under varying conditions. This chassis-mount component integrates two IGBT transistors, providing robust electrical isolation and mechanical stability for industrial power conversion systems.

Feature Summary

• Dual N-channel configuration within a single half-bridge module structure
• High voltage blocking capability up to 1700 V for robust circuit protection
• Chassis mount design ensuring secure mechanical integration
• Wide operating temperature range supporting extreme environmental conditions

Applications

• Industrial motor drives and variable frequency drives
• Uninterruptible power supply (UPS) systems
• Induction heating equipment
• Medium voltage DC-AC inverters

Procurement Notes

Verify the specific datasheet version before procurement, as Powerex product lines may undergo revisions. Confirm that the 1700V rating aligns with your system's voltage requirements, distinguishing it from lower-voltage variants like the CM100DY series. Ensure compatibility with standard chassis mounting hardware. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer to avoid supply chain disruptions during production.

Selection Notes

Select this module when a 1700V rating is required for high-voltage applications, unlike the 1200V CM100DY-24NF. Consider the 100A current limit for moderate power levels compared to higher-current options like the CM1000DU series. Evaluate thermal management needs given the 890W dissipation rating. Ensure the half-bridge topology fits your circuit design rather than full-bridge configurations. Verify gate drive voltage compatibility with standard IGBT drivers.

Part Context

The CM100DU-34KA belongs to Powerex’s IGBTMOD™ family, which specializes in insulated gate bipolar transistor modules for power electronics. This series is engineered for durability and efficiency in industrial settings. The 'DU' designation typically indicates a specific pinout and internal configuration distinct from other series like 'DY'. It represents a mature technology platform used in various power conversion architectures requiring high reliability and proven performance characteristics.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. For equivalent specifications, consider reviewing other Powerex modules with matching 1700V and 100A ratings, such as those in the CM100DU series with different suffixes, if pin compatibility allows. Always verify electrical parameters and mechanical dimensions against the original design requirements before substitution.
