The 92 V clamp ceiling means a 60 V bus sees the transient clipped before it reaches the downstream regulator's abs-max input. ## Sourcing an obsolete part Vishay lists this part as obsolete. Sourcing is through independent distribution — quantity and pricing confirmed at RFQ against the BOM line.","metaTitle":"Vishay 1.5KE68CA/54 TransZorb TVS, 1500W, 92V Clamp","metaDescription":"Vishay 1.5KE68CA/54 TransZorb TVS diode, 1500W peak pulse, 58.1V standoff, 92V clamp, bidirectional, DO-201AA.
