SCRs - Modules Procurement Notes

Verify the specific part number against official Littelfuse or IXYS documentation to confirm the 800V rating variant. Ensure that the procurement specifications align with the required thermal resistance values and mounting torque limits defined in the datasheet. Confirm compliance with RoHS directives and check for any recent product change notices that may affect component availability or specifications.

SCRs - Modules Selection Notes

Select this module when a compact single-phase rectifier solution is required for medium-power industrial applications. Consider the 32A continuous current rating and 800V blocking voltage as primary selection criteria. Evaluate the thermal resistance parameters to ensure adequate heat sinking is available. Verify that the operating environment falls within the specified junction temperature range and that mechanical constraints accommodate the ECO-PAC 1 package dimensions.
