The DO-201AA axial-lead package (also known as DO-27) is through-hole mounted, so it fits legacy board layouts and high-reliability designs where a soldered joint beats a surface-mount pad for vibration resistance.","metaTitle":"Littelfuse 1.5KE150-B Zener TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE150-B Zener TVS diode, 1500W peak pulse, 128V standoff, DO-201 axial.
