Procurement Notes
Verify the specific suffix and revision level against the manufacturer datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status directly with the supplier or official documentation before procurement. Check for any recent product change notices that may affect pinout or mechanical dimensions. Ensure the ordering quantity aligns with factory packaging constraints.
Selection Notes
Select this component when a 1400 V blocking voltage and 140 A continuous current are required in a standard TO-240AA footprint. Consider the 2.59 kA surge capability for circuit protection needs. Evaluate the thermal resistance characteristics relative to your heatsinking solution. Compare gate trigger specifications against your drive circuit capabilities to ensure reliable turn-on.
Part Context
This part belongs to the IXYS MCMA family of discrete semiconductor modules. These modules are characterized by their use of planar passivated technology and direct copper bonding to aluminum oxide substrates. The family targets high-reliability applications where long-term stability under line frequency conditions is critical. The TO-240AA form factor provides a standardized mounting interface for industrial power electronics.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching voltage and current ratings. Verify mechanical compatibility with existing PCB layouts or busbar connections. Ensure thermal performance metrics align with system cooling requirements.
