Procurement Notes

Verify the manufacturer origin as International Rectifier or Infineon, noting the acquisition history. Confirm the package type matches the specific ordering variant. Check for RoHS compliance status if required by local regulations. Ensure the component meets the specific voltage and current ratings for the target ignition application before integration.

Selection Notes

Select this component for applications requiring robust inductive switching with integrated clamp protection. The logic-level gate drive allows direct interfacing with standard microcontrollers without additional level shifting. Consider the thermal performance and packaging constraints when designing the heat dissipation strategy for coil-on-plug implementations.

Part Context

This IGBT belongs to the advanced process family from International Rectifier, now part of Infineon Technologies. It is specifically engineered for automotive environments where reliability under high stress is critical. The inclusion of internal clamps distinguishes it from standard discrete IGBTs, offering a more compact solution for ignition coils.

Replacement Considerations

Direct replacements may include other logic-level IGBTs with similar 40V ratings and integrated clamping features. Verify pinout compatibility and thermal resistance values. Cross-reference with Infineon's current automotive IGBT portfolio for updated equivalents.
