Procurement Notes
Verify the specific datasheet for the T820041404DH to confirm detailed electrical characteristics and mechanical dimensions. Ensure compatibility with existing thermal management solutions given the high current rating. Cross-reference official manufacturer documentation for any updates regarding pin configurations or material specifications before finalizing procurement plans.
Selection Notes
Select this component when a low-voltage, moderate-current SCR is required within the T82 family. Compare its 400 V rating against system voltage requirements to ensure adequate safety margins. Evaluate the 414 A RMS capability against load demands. Consider the disk button package for mounting constraints and thermal dissipation needs compared to other series options.
Part Context
This part belongs to the Powerex T82 series of silicon controlled rectifiers. These devices are characterized by their disk button packaging and ceramic-metal sealing technology. The series offers various current and voltage ratings to suit different industrial power applications, providing a standardized solution for high-reliability switching needs.
Replacement Considerations
Consult official substitution guides for compatible parts within the T82 series or equivalent manufacturers. Verify that alternative components match the 400 V reverse voltage and 414 A current ratings. Ensure physical package compatibility and terminal arrangements align with the existing design constraints.
