IXGN400N30A3

Overview

The IXGN400N30A3 is a high-power Insulated Gate Bipolar Transistor (IGBT) manufactured by IXYS. It belongs to the IXGX400N30 series and utilizes Silicon technology. The component is rated for a collector-emitter voltage of 300V and supports a continuous collector current of 400 Amps. It is housed in a tube package configuration. The product status is listed as obsolete or end-of-life, indicating it is no longer actively produced or stocked by major distributors.

Feature Summary

• High-current capability designed for heavy-duty power switching applications
• Robust silicon-based construction for thermal stability
• Single-chip IGBT architecture for efficient circuit integration

Applications

• Industrial motor drives and variable frequency drives
• High-power welding equipment inverters
• Uninterruptible power supply (UPS) systems

Procurement Notes

This component is officially classified as obsolete or end-of-life by the manufacturer. Availability is restricted to remaining stock from third-party distributors or secondary markets. Buyers should verify the authenticity and physical condition of units carefully, as lead times are unpredictable and genuine new-old-stock quantities are limited. Cross-referencing with current replacement models is recommended for new designs.

Selection Notes

Engineers selecting this part must account for its discontinued status when planning long-term production cycles. The 400A current rating at 300V requires careful thermal management design due to significant power dissipation. Verify that the TO-268 or similar package footprint matches the existing PCB layout, as pin configurations may differ slightly between legacy IXYS packages and modern equivalents.

Part Context

The IXGN400N30A3 is part of the IXGX400N30 family, which represents IXYS's high-current IGBT lineup. These devices were engineered for applications demanding high reliability under extreme electrical stress. The 'A3' suffix typically denotes specific packaging or testing variations within the standard 300V/400A class, though exact suffix definitions require the original datasheet.

Replacement Considerations

Direct replacements are scarce due to the obsolete status. Potential alternatives include other 300V/400A IGBTs from manufacturers like Infineon or Mitsubishi, provided they fit the mechanical constraints. Verify switching speed and saturation voltage compatibility before substitution.
