That 1500W rating is the energy it absorbs in a single pulse — enough for a typical industrial transient or an inductive kickback event on a 24V bus. Bidirectional construction (one channel) means it protects both polarities in a single package — useful on AC-coupled lines or where the surge polarity is unknown. Vishay lists this part as Obsolete. For a repair bench or a legacy BOM, the path is surplus or independent distribution — we source it against an RFQ, confirming availability and current pricing at quote time. The DO-201AA axial footprint is shared by many 1.5KE-family parts, so a pin-compatible replacement from the same series may exist, but no specific cross-reference is documented here.","metaTitle":"1.5KE24C-E3/54 Vishay TVS, 1500W, 19.4V Standoff","metaDescription":"Vishay 1.5KE24C-E3/54 TransZorb TVS, 1500W peak pulse, 19.4V standoff, 34.7V clamp.
