Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and thermal characteristics. Confirm AEC-Q101 compliance requirements match the target automotive application standards. Check for any recent product change notices that may affect mechanical dimensions or material composition before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring 1200 V blocking capability with moderate current handling in automotive settings. The TO-247-3 package facilitates efficient heat dissipation for high-power density designs. Ensure the gate drive circuit supports the specified voltage limits and switching speeds to maximize the device's efficiency benefits.

Part Context

This part belongs to STMicroelectronics' MS series of IGBTs, which are engineered for automotive power electronics. The series emphasizes reduced energy consumption in motor control and HVAC systems. It complements other ST automotive components by providing reliable switching performance under strict temperature and voltage constraints typical of modern vehicle architectures.

Replacement Considerations

Direct substitutes must match the 1200 V/40 A rating, TO-247-3 package, and AEC-Q101 qualification. Verify equivalent VCE(sat) and switching times to maintain system efficiency. Cross-reference with other trench gate field-stop IGBTs from the same manufacturer family for potential drop-in replacements.
