The 6.12 V minimum breakdown voltage and 5.8 V standoff make this part suited for protecting 5 V logic or low-voltage DC rails against surges that exceed the normal operating level but stay within the 1500 W dissipation envelope of the DO-201 package. ## Clamping parameters and thermal envelope The DO-201AA (DO-27) axial-lead package allows through-hole mounting on boards where the lead bend and body clearance need to match a standard 0.100-inch grid layout. ## Lifecycle reality for the BOM line For a line that already uses this part, the BOM position must be sourced through independent distribution or surplus channels; quantities and traceability are confirmed at RFQ time, not from factory stock.","metaTitle":"Littelfuse 1.5KE6.8C-B Zener TVS, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE6.8C-B bidirectional Zener TVS, 1500W peak pulse, 5.8V standoff, DO-201.
