Housed in a DO-201AA (DO-27) axial leaded package, also referred to as DO-201 by Littelfuse. The through-hole mounting suits point-to-point wiring or PCB insertion where the axial leads are bent and soldered into plated through-holes. Available on Tape & Reel (TR) — the axial leads are taped for automated insertion, but the reel quantity is not specified here; confirm the reel count with the supplier at quote time. Available through independent surplus and broker channels.","metaTitle":"1.5KE27 Littelfuse TVS Diode, 1500W, 23.1V Standoff","metaDescription":"Obsolete Littelfuse 1.5KE27 Zener TVS diode, 1500W peak pulse, 23.1V reverse standoff, DO-201.
