Breakdown occurs at a minimum of 17.1 V, and the clamping voltage is 25.2 V at the full 59.52 A peak pulse current. The clamp voltage is what appears across the protected load during a surge; the 25.2 V ceiling must stay below the downstream component's absolute maximum rating. ## Package, mounting, and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE18A-HF is a through-hole part that mounts into a standard 0.036-inch diameter hole on the PCB. The axial body is easy to hand-solder or wave-solder, and the polarity band identifies the cathode for unidirectional orientation. The wide range means derating is minimal across typical ambient conditions.","metaTitle":"Comchip 1.5KE18A-HF TVS Diode, 1500W, 15.3V Standoff, DO-201","metaDescription":"Comchip Technology 1.5KE18A-HF Zener TVS diode, 1500W peak pulse power, 15.3V reverse standoff, 59.52A Ipp. Active production, DO-201 axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Comchip Technology","Type":"Zener","Series":"1.5KE-HF","Package":"Tape & Box (TB)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.2V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"59.52A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3749","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9f43de99c350433b7129996d8f2ed805.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE18A-HF/alternatives.json"},"ai":{"faq":[{"question":"What is the peak pulse power rating of the 1.5KE18A-HF?","answer":"This rating defines the energy it can absorb during a transient event."},{"question":"What package does the 1.5KE18A-HF come in?","answer":"It is supplied in a DO-201AA (DO-27) axial leaded through-hole package, shipped in tape and box (TB) format."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/comchip-technology/1.5KE18A-HF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/comchip-technology/1.5KE18A-HF when reusing this data.
