Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest datasheet before procurement. Ensure that the component meets AEC-Q101 qualification requirements if intended for automotive-grade applications. Confirm thermal management specifications align with the target system's heat dissipation capabilities to maintain reliability within the specified operating temperature range.

Selection Notes

Select this component when designing circuits requiring a 390V rated IGBT with integrated gate protection. Consider the 300mJ single pulse energy absorption capability for applications involving inductive loads. Evaluate the D2PAK package constraints for PCB layout and thermal vias. Compare saturation voltage characteristics against alternative devices to optimize conduction losses in the specific operating frequency range.

Part Context

This part belongs to STMicroelectronics' portfolio of application-specific IGBTs optimized for automotive use. It is part of a series utilizing PowerMESH technology, which distinguishes it from standard general-purpose IGBTs by offering enhanced ruggedness and simplified external circuitry requirements due to integrated clamping features.

Replacement Considerations

Direct substitutes must match the 390V voltage rating, 25A current capacity, and D2PAK/SOT404 package. Verify that any replacement also includes internal gate-collector and gate-emitter clamping diodes to maintain equivalent protection levels. Check for AEC-Q101 qualification if the original design mandates automotive compliance.
