The 85.5 V reverse standoff voltage means it sits across a nominal 85 V rail and stays out of the way until a surge pushes it above the 90 V minimum breakdown threshold. ## Lifecycle reality — obsolete, sourced to order No stock-holding claim — sourced per request. ## Key ratings and what they mean for your board No power line protection rating — this is a signal-rail or low-voltage bus clamp, not designed for AC mains primary-side suppression.","metaTitle":"Littelfuse 1.5KE100 TVS Diode, 1500W, DO-201, Obsolete","metaDescription":"Littelfuse 1.5KE100 Zener TVS diode, 1500W peak pulse, 85.5V standoff, DO-201 axial.
