IXEH40N120

Overview

The IXEH40N120 is a single NPT3 IGBT in a TO-247 package. It features a collector-emitter voltage of 1200 V, a continuous collector current of 60 A at 25°C and 40 A at 90°C, and a saturation voltage of 2.4 V to 3.0 V. The device has a power dissipation of 300 W at 25°C and operates between -55°C and +150°C. Thermal resistance from junction to case is 0.42 K/W.

Feature Summary

• NPT3 technology providing low saturation voltage and positive temperature coefficient for easy paralleling
• Fast switching with short tail current optimized for resonant circuits
• Optional HiPerFRED diode offering fast reverse recovery and low forward voltage

Applications

• AC drives
• DC drives and choppers
• Uninterruptible power supplies (UPS)
• Switched-mode and resonant-mode power supplies
• Inductive heating cookers

Procurement Notes

Verify the specific suffix against official documentation to confirm component configuration. Confirm that the TO-247 outline dimensions match the required PCB footprint. Ensure thermal interface materials are compatible with the specified junction-to-case thermal resistance values during integration.

Selection Notes

Select this component for high-voltage applications requiring robust switching performance. Evaluate the thermal management requirements based on the 300 W power dissipation rating. Consider the optional diode variant if freewheeling capabilities are necessary for the circuit topology.

Part Context

This part belongs to the IXYS NPT3 IGBT family designed for industrial power conversion. It utilizes non-punch-through technology to ensure stable operation across varying temperatures. The TO-247 package provides an industry-standard mechanical form factor for through-hole mounting.

Replacement Considerations

Check datasheets for alternative NPT3 IGBTs with matching 1200 V ratings and comparable TO-247 packages. Verify pinout compatibility and thermal resistance specifications before substitution.
