Procurement Notes
Verify the specific datasheet revision and ordering suffixes directly with SanRex or authorized distributors before procurement. Confirm thermal interface requirements and mounting torque specifications (2.5-3.9 Nm per leg) to ensure proper mechanical installation. Check for RoHS compliance status and lead times as availability may vary by region.
Selection Notes
Select this component for circuits requiring fast recovery characteristics and high current density. Ensure the cooling solution maintains the junction temperature below 150°C under maximum load conditions. Verify that the system's reverse voltage peaks do not exceed the 600 V rating to prevent breakdown.
Part Context
This part belongs to the SanRex discrete semiconductor module portfolio, specifically designed for industrial power conversion. It utilizes silicon technology and screw-mount packaging for secure integration into high-power electronic assemblies.
Replacement Considerations
Consult official SanRex documentation for verified substitute part numbers. Cross-referencing requires matching voltage, current, and recovery time specifications precisely.
