IRGR4045DPBF

Overview

The IRGR4045DPBF is a 600V, 40A ultra-fast IGBT from International Rectifier's channel thin wafer technology series. It features a low saturation voltage of 1.6V and thermal resistance values ranging from 0.45 to 0.60 °C/W depending on the specific suffix variant (TO-247AC or TO-247AD). Designed for switching frequencies between 8kHz and 30kHz, it includes a 5µs short-circuit rating and positive Vce(on) temperature coefficient for parallel operation. The device operates up to 175°C junction temperature and complies with RoHS standards.

Feature Summary

• Utilizes channel thin wafer technology to reduce conduction and switching losses
• Optimized for ultra-fast switching applications in the 8kHz to 30kHz range
• Features positive Vce(on) temperature coefficient to facilitate safe parallel operation

Applications

• Uninterruptible Power Supplies (UPS)
• Solar Inverters
• Induction Heating Systems
• Industrial Motor Drives
• Welding Equipment

Procurement Notes

Verify the exact suffix (PBF vs EPBF) and package type (TO-247AC vs TO-247AD) against the datasheet table, as these determine the specific thermal resistance and pinout configuration. Confirm RoHS compliance status if required by the manufacturing process. Ensure the ordering part number matches the intended current rating variant within the IRGP46xx series family.

Selection Notes

Select this component for high-efficiency power conversion where low switching loss is critical. The 40A rating at 100°C suits moderate power density designs. Consider the specific thermal resistance value associated with the chosen package variant during heatsink design. Verify that the system's fault current does not exceed the 5µs short-circuit capability.

Part Context

This device belongs to International Rectifier's expanded 600V IGBT portfolio, which also includes the IRGP4650D (50A) and IRGP4660D (60A). All variants share the same core channel thin wafer architecture and packaging options, differing primarily in their continuous collector current ratings and corresponding thermal resistances.

Replacement Considerations

Direct functional replacements within the same manufacturer line include the IRGP4640D series variants. Cross-manufacturer substitution requires verifying matching voltage ratings (600V), current capacity (40A@100°C), and package dimensions (TO-247). Ensure the replacement device supports similar switching speeds and short-circuit withstand times.
