- High voltage thyristor/diode assemblies
Procurement Notes
Verify component authenticity through authorized Vishay distributors or direct manufacturer channels. Confirm that the specific part number matches the required 1000V and 75A specifications. Check for RoHS compliance status as indicated in official documentation, noting potential lead content variations. Ensure packaging integrity upon receipt to prevent damage to the ceramic insulator and terminal connections during handling and installation.
Selection Notes
Select this component for applications requiring high voltage isolation and robust thermal management in a standardized footprint. The integrated diode configuration simplifies circuit design by combining SCR and diode functions. Consider the 3500V RMS isolating voltage requirement when designing safety margins. Evaluate the mechanical compatibility with existing heatsink mounting systems due to the specific ADD-A-PAK generation V dimensions.
Part Context
This module belongs to the IRK.71 series of thyristor/diode and thyristor/thyristor power modules. The series is characterized by thick aluminum metal die and double stick bonding techniques. It represents Generation V of the ADD-A-pak module line, which combines excellent thermal performance using Direct Bonded Copper substrates with high surge capabilities.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Vishay cross-reference guides for compatible alternatives.
