The DO-201AA axial package suits through-hole mounting on boards where leaded components are preferred for mechanical robustness or thermal mass. The 1500 W peak pulse power rating (8/20 µs waveform also specified at 31.5 A) tells you the device can absorb a single high-energy transient without failing. For a 154 V rail, the 171 V breakdown gives a comfortable margin above the operating voltage, so the diode stays off during normal conditions and only conducts during an overvoltage event. The 317 V clamping voltage is the maximum voltage the load sees during the surge — ensure your downstream components are rated for at least that peak. Capacitance of 362.5 pF at 1 MHz is typical for a TVS of this power class; it is not designed for high-speed data lines but is fine for power and general-purpose I/O protection.","metaTitle":"1.5KE180CA TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"1.5KE180CA bidirectional TVS diode from STMicroelectronics, 1500W peak pulse power, 171V breakdown, DO-201 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"1.5KE, TRANSIL™","Package":"Cut Tape (CT); Tape & Box (TB)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE180","Operating Temperature":"-","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"362.5pF @ 1MHz","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"171V","Voltage - Clamping (Max) @ Ipp":"317V","Voltage - Reverse Standoff (Typ)":"154V","Current - Peak Pulse (10/1000µs)":"31.5A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/572f99690aeb2b0f302ed9cdcfd976ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE180CA/alternatives.json"},"ai":{"faq":[{"question":"What is the peak pulse power of 1.5KE180CA?","answer":"It is rated for 1500 W peak pulse power (1.5 kW) under a 10/1000 µs waveform, with a peak pulse current of 31.5 A for the 8/20 µs waveform."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/1.5KE180CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/1.5KE180CA when reusing this data.
