Procurement Notes

Verify the specific part number suffix against official SanRex documentation to ensure correct voltage and current ratings. Confirm that the isolation breakdown voltage meets system requirements. Check RoHS compliance status if restricted substances are a constraint. Ensure mounting torque specifications are followed during installation to maintain mechanical integrity and thermal performance.

Selection Notes

Select this component when a single-phase or three-phase bridge configuration is required with high voltage isolation. The series connection of internal elements reduces the need for multiple discrete components. Consider the thermal impedance and operating temperature range for heat sink design. Verify that the surge current rating exceeds potential transient loads in the target application circuit.
