Procurement Notes

Verify the exact ordering code suffix to confirm pin configuration and packaging type before procurement. Ensure that the component meets the required RoHS compliance standards for your target market. Cross-reference the datasheet revision date to guarantee access to the latest electrical specifications and mechanical drawings. Confirm availability through authorized distributors to avoid counterfeit risks.

Selection Notes

Evaluate the maximum operating junction temperature against your thermal management design constraints. Compare the total gate charge with your driver capabilities to ensure adequate switching speed. Assess the body diode reverse recovery characteristics if used in hard-switching topologies. Verify that the package footprint matches your PCB layout requirements for proper soldering and mechanical stability.

Part Context

This component belongs to STMicroelectronics' high-voltage MOSFET portfolio, which targets power conversion and motor drive markets. It complements other devices in the series offering similar voltage ratings but different current handling capabilities.
