Procurement Notes

Verify the specific part number suffix against official SanRex documentation to confirm the 800V rating. Confirm that the isolation breakdown voltage meets system requirements, as specified in the datasheet. Ensure thermal management solutions align with the stated junction-to-case thermal impedance limits. Cross-reference mechanical dimensions and mounting torque specifications before integration.

Selection Notes

Select this component when an 800V blocking capability is required alongside a 160A continuous current rating. The series configuration allows for efficient bridge connections in single or three-phase topologies. Consider the 150°C maximum junction temperature for high-temperature environments. Verify that the 2500V isolation rating satisfies safety standards for the intended application voltage levels.
