Procurement Notes

Verify the specific suffix 'HP' against the official STMicroelectronics datasheet to confirm pinout compatibility and exact electrical tolerances. Ensure the procurement channel provides genuine components with traceable lot codes to prevent counterfeit risks in high-reliability power electronics assemblies.

Selection Notes

Select this component when designing circuits requiring 1700 V isolation with moderate current handling. Compare its switching speed and gate charge specifications against standard IGBTs or MOSFETs to determine suitability for the target frequency range and thermal management constraints of the final application.

Part Context

This part belongs to the ESBT family, which integrates MOS and bipolar technologies. It serves as an alternative to traditional IGBTs in applications where lower conduction losses are critical. The TO-247-4L package facilitates mounting on heatsinks for effective thermal management in industrial power modules.

Replacement Considerations

Consult STMicroelectronics documentation for direct cross-reference models. Verify that any substitute maintains identical pin configuration and voltage ratings to ensure circuit compatibility without redesign.
