Mosorb™ series Zener TVS diode, 1.5KE68ARL4G, 1500W peak pulse power, 58.1V reverse standoff, 92V clamping, DO-201AD axial, through hole.","salesMarkdown":"## TVS clamp for 48 VDC rails and telecom buses The 1.5KE68ARL4G: Its 58.1 V reverse standoff voltage (working voltage) means it sits across a 48 V nominal rail without conducting in normal operation, then clamps transients at 92 V maximum — well below the typical 100 V abs-max of downstream DC-DC converters and POL regulators. The breakdown voltage range starts at 64.6 V minimum, so the device begins to avalanche before the clamping voltage is reached. This gives the TVS a defined trigger point for repetitive surge events on telecom or industrial DC buses. ## DO-201AD axial — board-fit and thermal path The single unidirectional channel protects one signal or power rail. For bidirectional clamping on AC-coupled lines or bipolar supplies, two devices back-to-back or a bidirectional variant from the same Mosorb™ family would be needed. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1.5KE68ARL4G as obsolete. No official successor order code is recorded in the lifecycle documentation. For a sustainment program or a repair depot that needs this exact clamp voltage and package, the part is available to order. The 58.1 V standoff and 92 V clamp are the critical fit parameters to match against the protected rail's transient profile.","metaTitle":"1.5KE68ARL4G Littelfuse TVS Diode, 1500W, 58.1V Standoff","metaDescription":"Littelfuse 1.5KE68ARL4G Mosorb™ Zener TVS, 1500W peak pulse, 58.1V reverse standoff, DO-201AD axial.
