Procurement Notes

Verify the specific suffix N1 against the manufacturer's latest datasheet to confirm pinout and mechanical dimensions. Ensure compatibility with existing cooling solutions given the module's weight and thermal requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when an 800V rating is sufficient and a 220A continuous current is required. Compare the forward voltage drop against system efficiency targets. Evaluate the Y2-DCB package size against available board space or chassis mounting constraints. Consider the thermal resistance characteristics relative to your heatsink design capabilities.

Part Context

This module belongs to the MDD220 series from IXYS, which focuses on high-power discrete semiconductor solutions.
