The DO-201AA axial package (also known as DO-27) is a through-hole form factor — you solder it into a board or wire it into a terminal block. ## Lifecycle reality and sourcing this part For a BOM line that calls out this exact part, supply runs through independent distribution channels. Availability and pricing are confirmed per RFQ; quantities are lot-specific.","metaTitle":"Littelfuse 1.5KE27A TVS Diode, 1500W, 23.1V Standoff","metaDescription":"Littelfuse 1.5KE27A Zener TVS diode, 1500W peak pulse power, 23.1V reverse standoff, DO-201 package.
