Procurement Notes

Verify the specific suffix 'RTP' against official Littelfuse documentation to confirm packaging type and compliance status. Ensure the ordering quantity aligns with manufacturer minimums. Cross-reference the datasheet revision date to guarantee parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when a 10 A RMS current rating and 400 V blocking voltage are required in a TO-220-2 package. Compare gate sensitivity requirements against alternative packages like TO-263 if surface mount is preferred. Verify thermal management needs against the specified operating temperature range.

Part Context

This part belongs to the Littelfuse Sxx10xSx series of thyristors. These devices are designed for general-purpose power control applications. The series offers various package options including through-hole and surface-mount configurations to suit different PCB layout constraints.

Replacement Considerations

Check for direct substitutes within the same Sxx10xSx family that may offer different packaging or slight parameter variations. Ensure any replacement maintains the 400 V and 10 A ratings.
