Procurement Notes

Verify the specific suffix GRP against official Littelfuse documentation to confirm package type and tape/reel specifications. Ensure that the selected variant matches the required breakover voltage tolerance and current ratings for the target application. Cross-reference datasheet revisions to confirm compliance with current environmental standards and pinout configurations before finalizing procurement orders.

Selection Notes

Select this component when a precise 120–138 V breakover threshold is required for bidirectional protection. Consider the DO-15 package size for through-hole mounting constraints. Evaluate the 1 A peak current capability against expected surge levels. Ensure the operating temperature range aligns with the environmental conditions of the end-use equipment to maintain reliability.
