IRSM515-044PA

Overview

The IRSM515-044PA is a smart power module integrating an Infineon CoolMOS™ CF7 650V N-channel MOSFET with an OptiMOS™ 3 half-bridge gate driver. It features a 4.5A peak source/sink current, integrated bootstrap diode, and active Miller clamp. The device includes comprehensive protection mechanisms such as desaturation detection, overcurrent protection, under-voltage lockout, and thermal shutdown. Packaged in a robust industry-standard TO-247-4L case for high-power applications.

Feature Summary

• Integrated CoolMOS™ CF7 technology for low switching losses
• Active Miller clamp prevents false turn-on during fast dv/dt events
• Desaturation detection enables fast short-circuit protection
• Thermal shutdown safeguards against overheating

Applications

• Motor drives and inverters
• Switched-mode power supplies (SMPS)
• Industrial motor control systems

Procurement Notes

Verify the specific suffix 'PA' to confirm package type and tape/reel specifications. Confirm RoHS compliance status and check for lead-free marking on the component body. Ensure the ordering part number matches the exact voltage rating and pin configuration required by the design.

Selection Notes

Select this module when high voltage isolation and integrated protection are required in a single package. The integrated gate driver simplifies layout compared to discrete solutions. Consider the thermal resistance of the TO-247-4L package for heat sink sizing. Verify that the input logic levels are compatible with the driving microcontroller or DSP.

Part Context

This component belongs to the IRSM515 family of smart power modules from International Rectifier, now part of Infineon Technologies. These modules combine high-voltage power semiconductors with intelligent gate drive circuitry to simplify system design and improve reliability in power conversion applications.

Replacement Considerations

Check for direct replacements within the IRSM515 series with different current ratings or package variants. Verify compatibility with existing PCB footprints and thermal management solutions before substituting.
