IXBF32N300

Overview

The IXBF32N300 is a high-voltage IGBT featuring a 3000V collector-emitter breakdown voltage and a 40A continuous collector current. It utilizes the ISOPLUS i4-PAC™ package with an isolated mounting surface for thermal management. Key electrical parameters include a maximum pulse current of 250A, a typical saturation voltage of 3.2V at 32A, and a gate charge of 142nC. The device operates within a junction temperature range of -55°C to 150°C and dissipates up to 160W of power.

Feature Summary

• Utilizes Silicon Chip on Direct-Copper Bond (DCB) substrate technology for enhanced thermal performance and reliability.
• Features an isolated mounting surface providing 3000V electrical isolation between the case and circuit ground.
• Designed as a high-gain BiMOSFET monolithic bipolar MOS transistor to minimize gate drive requirements.

Applications

• Switched-Mode and Resonant-Mode Power Supplies
• Uninterruptible Power Supplies (UPS)
• Laser Generators
• Capacitor Discharge Circuits
• AC Switches

Procurement Notes

Verify the specific manufacturer designation, as IXYS components are now distributed under Littelfuse branding. Confirm that the ISOPLUS i4-PAC™ package matches your board layout requirements, specifically noting the three-lead configuration. Ensure the 3000V rating aligns with your system's peak voltage stresses and that the thermal resistance characteristics support your heat sink design for the specified 160W dissipation limit.

Selection Notes

Select this component when high blocking voltage is required alongside moderate current handling in a compact form factor. The low gate charge facilitates efficient driving in high-frequency applications. Consider the DCB substrate construction for superior thermal cycling robustness compared to standard wire-bonded devices. Evaluate the trade-off between the 3.2V saturation voltage and switching speed based on the specific efficiency targets of the power conversion topology.

Part Context

This device belongs to the IXBF series of high-voltage BiMOSFET transistors manufactured by IXYS Corporation. These components are engineered for demanding power electronics environments requiring high voltage isolation and gain. The series represents a specialized segment of power semiconductors designed to bridge the gap between standard MOSFETs and traditional IGBTs in high-voltage regimes.

Replacement Considerations

Cross-reference with other IXBF series variants such as the IXBF20N300 or IXBF12N300 for different current ratings within the same voltage class. Verify pinout compatibility and thermal interface dimensions before substituting with equivalent parts from other manufacturers offering similar 3000V IGBT specifications.
