The DO-201 supplier device package footprint is standard across the 1.5KE family, so the PCB layout is shared if you need to swap between voltage variants in the same series. ## Lifecycle reality — obsolete, but available through independent channels The 1.5KE series includes many voltage variants, but a direct drop-in replacement requires matching the 477V standoff and 1500W rating — parametric substitution is possible but not confirmed as a formal second-source. ## Sourcing posture — quoted to order against RFQ Because the part is obsolete, availability is lot-specific and confirmed at quote time. We source through franchised excess and independent distribution — each reel carries traceability back to the original manufacturer. No stock-holding claim; pricing and lead time are confirmed against your BOM quantity when you submit an RFQ.","metaTitle":"Littelfuse 1.5KE530 TVS Diode, 1500W, 477V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE530 Zener TVS diode, 1500W peak pulse power, 477V standoff, 761.25V clamping.
