Packaged in a DO-201AA (DO-27) axial leaded body, it mounts through-hole and handles 83.5A peak pulse current at the clamping voltage. ## Obsolete — sourcing through independent channels Littelfuse lists the 1.5KE13-B as obsolete. No official successor order code is recorded in the lifecycle data. For existing BOM lines that still call out this part number, availability is limited to surplus and broker inventory sourced through independent distribution. Each lot is verified for authenticity and traceability before shipment.","metaTitle":"Littelfuse 1.5KE13-B TVS Diode, 1500W, 11.1V Standoff","metaDescription":"Littelfuse 1.5KE13-B Zener TVS, 1500W peak pulse, 11.1V reverse standoff, DO-201 axial.
