Overview
The CM50BU-24H is a four-element IGBT module from the U-Series, rated for 1200V collector-emitter voltage and 50A continuous collector current. It integrates four N-channel IGBTs in an H-bridge configuration, each paired with a discrete super-fast recovery free-wheel diode featuring a 70ns reverse recovery time. The device operates within a junction temperature range of -40°C to 150°C and provides 2500V isolation between main terminals and the baseplate. Key electrical parameters include a typical VCE(sat) of 2.9V at 25°C and a total gate charge of 187nC.
Feature Summary
- Four IGBT transistors configured in an H-bridge topology with integrated anti-parallel free-wheel diodes
- Discrete super-fast recovery diodes providing 70ns reverse recovery characteristics
- Electrically isolated baseplate design facilitating simplified thermal management and system assembly
Applications
- AC motor control systems
- Motion and servo control drives
- Uninterruptible power supplies (UPS)
- Welding power supplies
- Laser power supplies
Procurement Notes
Verify the specific ordering suffix against official Powerex documentation to confirm terminal configurations and mechanical variations. Ensure compatibility with required mounting torque specifications: 15 in-lb for M4 main terminals and 31 in-lb for M5 mounting points. Confirm that the component meets necessary environmental standards for the intended operating temperature range.
Selection Notes
Select this module for applications requiring high-voltage switching with integrated freewheeling capabilities. Evaluate thermal resistance values, specifically 0.31°C/W for the IGBT and 0.7°C/W for the diode, against the system's heat sinking capacity. Consider the peak collector current rating of 100A for transient load conditions while ensuring junction temperatures remain within the specified limits.
Part Context
This component belongs to the Powerex IGBTMOD™ U-Series, designed for robust switching applications. The series emphasizes low drive power requirements and reduced saturation voltage to enhance efficiency. The modular construction allows for direct integration into power electronics without complex discrete component assembly.
Replacement Considerations
Consult official cross-reference guides for verified substitutes. Ensure replacement modules match the 1200V/50A rating, H-bridge configuration, and physical footprint dimensions to maintain system compatibility.
