IRG4PSC71KD

Overview

The IRG4PSC71KD is a single N-channel Insulated Gate Bipolar Transistor (IGBT) manufactured by Infineon Technologies. It features a maximum collector-emitter voltage of 600 V and a continuous collector current rating of 85 A at 25 °C. The device utilizes the Super-247 (TO-274AA) through-hole package, which supports a power dissipation capacity of 350 W. Key electrical parameters include a collector-emitter saturation voltage of 2.3 V and a gate-emitter voltage range of -20 V to +20 V. The component operates within a junction temperature range from -55 °C to +150 °C.

• Industrial welding equipment
• Uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and packaging details. Confirm availability as distribution channels may vary. Ensure compatibility with existing thermal management designs due to the TO-274AA form factor. Cross-reference datasheet revisions to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring robust 600 V blocking capability and high current handling in a standard through-hole footprint. Evaluate thermal resistance requirements to ensure the Super-247 package meets the system's heat dissipation needs. Consider the 2.3 V saturation voltage for efficiency calculations in conduction loss scenarios. Verify that the drive circuitry can support the specified gate-emitter voltage limits safely.

Part Context

This part belongs to the IRG4PSC71K series of ultra-fast IGBTs from Infineon Technologies. It is engineered for high-efficiency power conversion where fast switching speeds are critical. The Super-247 package provides a balance between high current density and ease of assembly compared to surface-mount alternatives. It serves as a discrete solution for medium-to-high power industrial electronics.

Replacement Considerations

Consult official replacement guides or cross-reference tables for verified substitutes. Ensure any alternative maintains equivalent voltage, current, and thermal ratings. Verify pinout compatibility if direct board replacement is required without layout modifications.
