For existing designs, the part is available through independent surplus and broker channels. Sourcing is confirmed per RFQ — quantities are lot-specific and not guaranteed for continuous supply. ## Surge protection envelope — 1500W at 11.1V standoff That clamping voltage is what the downstream circuitry sees during the event — a 12V rail with 20V-tolerant components is safe here. A single bidirectional device protects both positive and negative transients, saving board space versus two unidirectional diodes back-to-back. ## Package and field-service reality Housed in a DO-201AA (DO-27) axial leaded package — through-hole mount, easily swapped on a bench or in the field with basic tools. No hot-air station needed, no reflow profile to manage. Not rated for AC mains primary protection — this is a secondary-side or DC rail suppressor.","metaTitle":"Littelfuse 1.5KE13C-B TVS Diode, 1500W, 11.1V Standoff","metaDescription":"Obsolete Littelfuse 1.5KE13C-B bidirectional TVS diode, 1500W peak pulse power, 11.1V standoff, DO-201 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"11.75V","Voltage - Clamping (Max) @ Ipp":"19.11V","Voltage - Reverse Standoff (Typ)":"11.1V","Current - Peak Pulse (10/1000µs)":"83.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest alternative to 1.5KE13C-B in the same family?","answer":"No official pin-compatible successor is recorded from Littelfuse for this specific bidirectional 11.1V standoff variant.
