The 1.5KE120CA is marked obsolete by STMicroelectronics. ## Key ratings for the protection design The 212V clamping voltage is the maximum voltage the load sees during the surge; ensure downstream components have adequate margin above this level. The 500pF capacitance at 1MHz is moderate — acceptable for power lines and low-speed signals, but may load high-frequency data lines.","metaTitle":"1.5KE120CA STMicroelectronics TRANSIL™ TVS, 1500W","metaDescription":"STMicroelectronics 1.5KE120CA bidirectional TVS diode, 1500W peak pulse power, 102V standoff, 212V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"500pF @ 1MHz","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"114V","Voltage - Clamping (Max) @ Ipp":"212V","Voltage - Reverse Standoff (Typ)":"102V","Current - Peak Pulse (10/1000µs)":"47A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/572f99690aeb2b0f302ed9cdcfd976ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE120CA/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for 1.5KE120CA?","answer":"A functionally similar bidirectional TVS with a 102V standoff and 212V clamping in a DO-201 package should be selected based on the specific circuit requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/1.5KE120CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/1.5KE120CA when reusing this data.
