IRGP4078D-EPBF

Overview

The IRGP4078D-EPBF is an Insulated Gate Bipolar Transistor (IGBT) with a co-packaged ultra-low forward voltage diode, designed for induction heating and soft switching applications. It features a 600V collector-emitter breakdown voltage and a continuous collector current of 76A at 100°C. The device utilizes trench technology to minimize conduction and switching losses. Key electrical parameters include a maximum Vce(on) of 2.3V at 75A and a short-circuit rating of 10 microseconds. It operates within a junction temperature range up to 175°C and is housed in a TO-247AD package.

Feature Summary

• Integrated ultra-low forward voltage diode optimized for high-efficiency soft switching
• Trench gate technology reduces both conduction and switching energy losses
• Robust 10-microsecond short-circuit withstand capability ensures system reliability
• Positive temperature coefficient of Vce(on) facilitates safe parallel operation

Applications

• Induction heating systems
• Soft switching power converters
• High-frequency resonant circuits
• Uninterruptible power supplies (UPS)

Procurement Notes

Verify the specific suffix against official datasheets to confirm RoHS compliance and lead-free status. Confirm package variant accuracy as distributors may list multiple mechanical options. Request batch-specific test reports to validate short-circuit ratings and thermal performance before integration into critical designs.

Selection Notes

Select this component when low diode forward voltage is critical for efficiency in resonant topologies. Ensure the driver circuit supports the required gate charge and switching speeds. Verify that the thermal management solution can handle the specified power dissipation at the target operating frequency and ambient temperature conditions.

Part Context

This part belongs to International Rectifier's high-performance IGBT portfolio, now under Infineon Technologies. It represents a specialized niche focusing on ultra-fast recovery and low-loss characteristics for demanding power conversion environments where standard IGBTs may exhibit higher switching losses or inadequate diode performance.

Replacement Considerations

Direct substitutes include the IRGP4078DPBF (non-EPBF variant) and potentially the IRGP4068DPBF if slightly different electrical margins are acceptable. Cross-compatibility requires verification of pinout consistency and thermal resistance values. Always consult the manufacturer's latest replacement guide for obsolescence notices.
