SCRs - Modules Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm RoHS compliance status and specific manufacturing lot details against the official datasheet. Check for obsolescence notices as this product line may have limited availability. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage prior to assembly.

SCRs - Modules Selection Notes

Select this module when a 1600V rating and 162A continuous current capacity are required in a screw-mount configuration. Evaluate thermal management requirements based on the 0.2 K/W junction-to-case resistance. Compare gate drive specifications, specifically the 150 mA trigger current, against available driver circuits. Consider the 125°C maximum junction temperature limit for system reliability calculations.

SCRs - Modules Part Context

This component belongs to the TT162N series of thyristor modules by Infineon Technologies. It shares the TD162N mechanical footprint but differs in internal topology and electrical ratings compared to diode-thyristor combinations like the TD162N16KOF. The KOFA suffix indicates specific packaging and labeling variations within the standard TT162N family.

SCRs - Modules Replacement Considerations

Direct replacements include the TT162N16KOF and TT162N16KOFTIMHPSA1. Verify pinout compatibility and exact electrical parameter tolerances before substitution. Alternative packages such as the SB20 or PB50SB-1 require mechanical redesign.
