Housed in a DO-201AA (DO-27) axial leaded package, it mounts through a plated hole and takes solder or clip-in retention — no reflow profile to manage, and the junction operates from -55°C to 175°C, covering the full industrial temperature envelope including hot cabinet interiors. ## Obsolete — sourcing through independent channels Littelfuse lists the 1.5KE16-B as obsolete. No official successor order code is recorded; the 1.5KE series continues with active variants at different standoff voltages, but this specific 13.6V reverse standoff part is no longer in factory production. We source and quote it against an RFQ — availability is lot-specific and confirmed at quote time, with no minimum order quantity assumed. ## Board-fit and cross-reference note The DO-201AA axial footprint is shared across the 1.5KE series — a 1.5KE16A (bidirectional) or a 1.5KE15A (lower standoff) will drop into the same hole pattern, but the clamping threshold shifts. Bulk packaging means the parts ship loose in an antistatic bag or tube — no reel or tape for automated insertion. Store in a dry, ESD-safe cabinet; the axial leads are tin-plated and solder readily with a standard iron or wave pot.","metaTitle":"Littelfuse 1.5KE16-B TVS Diode, 1500W, 13.6V Standoff","metaDescription":"Littelfuse 1.5KE16-B Zener TVS diode, 1500W peak pulse, 13.6V reverse standoff, DO-201AA axial.
