IXYH40N120A4

Overview

The IXYH40N120A4 is a discrete Insulated Gate Bipolar Transistor (IGBT) from the IXYS XPT GenX4 series. It utilizes XPT thin wafer technology and features a trench gate design for optimized performance. The device is rated for a collector-emitter voltage of 1200V and operates in a single configuration. It supports continuous collector currents up to 75A at 25°C, with a maximum power dissipation of 380W. The component functions within a temperature range of -55°C to +150°C and is housed in a TO-247AD-3 package.

Feature Summary

• Employs XPT thin wafer technology to achieve low saturation voltage and reduced conduction losses.
• Features a fourth-generation trench gate structure designed for high switching frequencies up to 5kHz.
• Provides high power density combined with low gate drive requirements for efficient circuit integration.

Applications

• Power inverters
• Motor drives
• PFC circuits
• Battery chargers
• Welding machines

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet before procurement. Confirm that the TO-247AD-3 package dimensions match the target PCB footprint. Ensure thermal management solutions are compatible with the specified power dissipation limits. Check for any recent lifecycle status changes or obsolescence notices directly from Littelfuse or authorized distributors.

Selection Notes

Select this component when designing systems requiring 1200V blocking capability with moderate current handling around 75A. The XPT GenX4 technology offers a balance between low conduction loss and fast switching suitable for frequencies near 5kHz. Compare the TO-247AD-3 package constraints against available board space and heatsinking options relative to alternative packages like standard TO-247.

Part Context

This part belongs to the IXYS XPT GenX4 family of IGBTs, which are engineered for high-efficiency power conversion. The series emphasizes low V_CE(sat) and robust operation across wide temperature ranges. It serves as a key switching element in medium-power industrial applications where reliability and thermal performance are critical design parameters.

Replacement Considerations

Direct substitutes include other IXYS IXYH40N120 variants with identical pinouts and electrical ratings. Verify compatibility with existing gate driver specifications if replacing with different generation trench IGBTs. Cross-reference thermal resistance values to ensure equivalent heat sinking requirements are met.
