The 1.5KE series covers a broad voltage range, so a parametric replacement (different breakdown voltage) may exist within the same family, but no pin-compatible drop-in is documented. A board-level review of the clamping and standoff requirements is advised before substituting. ## Temperature range and general-purpose deployment The general-purpose application classification means no specific automotive or military screening — the part is a standard off-the-shelf TVS for board-level transient suppression.","metaTitle":"Littelfuse 1.5KE18 TVS Diode, 1500W, 15.3V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE18 Zener TVS diode, 1500W peak pulse power, 15.3V reverse standoff, 60.3A peak current.
