DIACs, SIDACs Procurement Notes

Verify the specific suffix RP3 confirms the tape and reel packaging configuration against the official Littelfuse datasheet. Ensure the breakover voltage tolerance aligns with the 190 V to 215 V specification required by your circuit design. Cross-reference the RoHS and REACH-SVHC compliance status directly from the manufacturer's documentation prior to final procurement approval.

DIACs, SIDACs Selection Notes

Select this component when a precise breakover voltage between 190 V and 215 V is required for triggering applications. The 1 A RMS current rating and 20 A peak capability suit moderate energy surge scenarios. Consider the TO-92 form factor implications if transitioning from bulk to reel packaging, ensuring compatibility with existing assembly processes and thermal management requirements.

DIACs, SIDACs Part Context

This part belongs to the Kxxxzy series of Sidacs manufactured by Littelfuse Inc. These components are specialized high-voltage trigger diodes distinct from standard DIACs, offering higher energy handling capabilities. The series is engineered for industrial and consumer electronics protection, providing reliable switching behavior under transient voltage conditions.

DIACs, SIDACs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other K-series Sidacs only if datasheet parameters match exactly.
