SCRs - Modules Procurement Notes

Verify the specific suffix against official Infineon documentation to confirm exact rating variations. Confirm RoHS compliance status and check for obsolescence notices via authorized distributors. Ensure mounting hardware compatibility with the TO-200AA footprint before procurement.

SCRs - Modules Selection Notes

Select this component based on the required 1200 V blocking capability and 470 A continuous current load. Evaluate thermal management requirements to maintain junction temperatures within the specified 125°C limit under full load conditions. Verify gate drive circuitry can supply the necessary trigger voltage and current specifications.

SCRs - Modules Part Context

This part belongs to the T470N series of thyristor modules from Infineon Technologies. The series offers various voltage ratings including 1200 V, 1400 V, and 1600 V options, all sharing similar mechanical dimensions and current capacities for standardized design integration.

SCRs - Modules Replacement Considerations

Direct replacements may include other T470N variants with matching voltage ratings such as T470N14 or T470N16, provided the higher voltage ratings do not conflict with system constraints. Cross-brand equivalents require verification of pinout and thermal characteristics.
