This is a heads-up for any BOM that uses this order code: the window for factory orders is closing, and once the remaining inventory clears, new supply will come only from surplus or broker channels. ## Clamping performance and fit check For a 12 V rail that sees transients above the normal operating level, the 15.3 V standoff gives headroom while the 25.2 V clamp keeps the spike within the downstream device's abs-max rating — provided the trace inductance and the TVS's own response time are accounted for in the layout. Housed in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The axial leads suit point-to-point wiring or PCB through-holes; the body length and lead diameter match standard 1.5KE-series footprints.","metaTitle":"1.5KE18A-E3/51 Vishay TransZorb TVS, 1.5kW, 15.3V","metaDescription":"Vishay 1.5KE18A-E3/51 TransZorb TVS diode, 1500W peak pulse, 15.3V standoff, DO-201AA.
