Available through independent surplus and broker inventory — quantities and pricing confirmed at RFQ. ## DO-201 axial package and temperature range Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), rated for through-hole mounting. Tape and Reel packaging available.","metaTitle":"Littelfuse 1.5KE170 TVS Diode, 1500W, 145V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE170 Zener TVS diode, 1500W peak pulse power, 145V reverse standoff, DO-201 axial.
