Procurement Notes
Verify the specific suffix 'TA' against the manufacturer datasheet to confirm exact pinout and mechanical dimensions. Confirm RoHS compliance status directly with the supplier documentation. Ensure the TO-240AA package matches your heatsink interface requirements. Check for any specific handling instructions regarding the ceramic substrate integrity during installation.
Selection Notes
Select this component when a 140A RMS current rating and 1200V blocking voltage are required in a compact TO-240AA form factor. Consider the 2.59kA surge capacity for transient protection needs. Evaluate the 200mA gate drive requirements against your control circuit capabilities. Compare thermal resistance characteristics if operating near the 140°C limit.
Part Context
This part belongs to the IXYS MCMA family of thyristor modules. These modules are engineered for industrial power electronics, combining high current density with reliable thermal performance. The TO-240AA package is a standard industry footprint, facilitating integration into existing designs requiring medium-power SCR solutions.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in thermal resistance or gate sensitivity. Verify that any replacement maintains the same TO-240AA pin configuration and voltage/current ratings to ensure circuit compatibility.
