The DO-201AA axial package (also known as DO-27) is through-hole mounted, suited for point-of-entry protection on power lines where board space allows a leaded part. ## Obsolete — sourced through independent channels Littelfuse lists the 1.5KE47 as Obsolete.","metaTitle":"1.5KE47 Littelfuse TVS Diode, 1500W, 40.2V Standoff, DO-201","metaDescription":"1.5KE47 Littelfuse Zener TVS, 1500W peak pulse, 40.2V reverse standoff, 68.04V clamp.
