Procurement Notes

Verify the specific suffix NO1 against the manufacturer's latest datasheet to confirm pinout configuration and packaging details. Ensure compatibility with existing heatsinking solutions due to the TO-240AA form factor. Check for RoHS compliance status if required by local regulations. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component for applications requiring moderate current handling up to 40A with high voltage blocking capabilities. The TO-240AA package offers space efficiency compared to larger modules while maintaining reliable thermal dissipation. Consider the 3600V isolation rating when designing circuits with significant potential differences between power stages and control logic.

Part Context

This part belongs to IXYS' family of thyristor modules, which are engineered for demanding power electronics environments. The series typically includes variants with different voltage and current ratings, sharing common packaging standards like the TO-240AA. These modules are integral to industrial power conversion and control systems where durability and thermal stability are critical.

Replacement Considerations

Direct replacements must match the 800V/40A rating and TO-240AA footprint. Verify that alternative devices offer comparable isolation voltages and thermal resistance values. Ensure the replacement supports similar gate trigger requirements to maintain circuit functionality without modification.
