Procurement Notes
Verify the specific part number suffix against official documentation to confirm voltage ratings, as variants exist within the series. Confirm mounting torque specifications (2.5-3.9 N·m) and terminal requirements during integration. Ensure thermal management aligns with the specified junction-to-case thermal impedance and operating temperature range of -40°C to +150°C.
Selection Notes
Select this component for applications requiring fast switching speeds and high current handling in isolated environments. Consider the 2000 V rating for high-voltage systems and verify that the 400 A continuous current meets load requirements under appropriate cooling conditions. Evaluate the surge capability for transient protection needs.
