Sourcing now runs through independent surplus and broker channels — availability and date-code spread are confirmed at RFQ against the BOM quantity. ## DO-201 axial package — through-hole fit for legacy and industrial boards The DO-201AA / DO-27 axial package (supplier device package DO-201) is a through-hole form factor with a 0.052-inch lead diameter typical. The junction operates from -55°C to 175°C, covering military and industrial temperature envelopes. Power line protection is not built in — this is a signal-rail or low-impedance bus protector, not a mains-grade suppressor. ## Bidirectional — one diode covers both polarities A single bidirectional channel clamps positive and negative transients symmetrically. For a 111V rail, this means one device replaces two unidirectional TVS diodes back-to-back, saving board area and BOM line count. The 1500W peak pulse rating (8.5A at the 10/1000µs test waveform) sets the surge-handling ceiling — derate for shorter or repetitive pulses per the datasheet curve.","metaTitle":"Littelfuse 1.5KE130C-B TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE130C-B bidirectional TVS diode, 1500W peak pulse power, 111V standoff, DO-201 axial.","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)":"117.45V","Voltage - Clamping (Max) @ Ipp":"187.95V","Voltage - Reverse Standoff (Typ)":"111V","Current - Peak Pulse (10/1000µs)":"8.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/149eca2cbf10498ecc0c7eab912fe9f4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I source the 1.5KE130C-B for a BOM line?","answer":"Submit an RFQ for the required quantity and packaging condition."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE130C-B","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE130C-B when reusing this data.
