The minimum breakdown voltage of 17.1V guarantees the TVS starts conducting before the protected circuit's absolute maximum rating is reached, given a typical 12V rail with a 16V abs-max input. ## Package and temperature envelope for the DO-201AA axial TVS Housed in a DO-201AA (DO-27) axial-lead package with through-hole mounting, this TVS suits point-to-point wiring or PCB layouts where the lead bend and body length must fit existing board keep-outs — the 1.5KE package code is the supplier device package reference.","metaTitle":"Vishay 1.5KE18CA/54 TransZorb TVS, 1.5kW, 15.3V Standoff","metaDescription":"Obsolete Vishay 1.5KE18CA/54 bidirectional Zener TVS diode, 1500W peak pulse power, 15.3V reverse standoff.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Reel (TR)","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":"1.5KE18","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.2V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"59.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE18CA%2F54/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1.5KE18CA/54 come in?","answer":"It comes in a DO-201AA (DO-27) axial-lead through-hole package, identified by the supplier device package code 1.5KE."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE18CA-54","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE18CA-54 when reusing this data.
