It is rated for continuous junction temperatures from -55°C to 175°C, covering the under-hood ambient range with margin. ## Clamping performance and pulse current capability For a 12V system that sees a 150V load-dump transient, the TVS shunts the energy and holds the rail below 15V — well within the 36V abs-max of most automotive-rated ECUs and sensors. The 1500W peak pulse rating is the product of clamp voltage and peak current at the test waveform. In a real application, the actual power dissipated depends on the surge duration and source impedance; the 10/1000µs waveform is a standard telecom surge, but the same device handles shorter automotive transients (ISO 7637-2 pulses) with higher peak current capability. ## Package and board integration Housed in the DO-201AA (DO-27) axial-lead package, with the DO-201 as the supplier device package designation. Through-hole mounting suits point-to-point wiring, terminal blocks, or PCB layouts where the axial body is soldered into plated through-holes. ## Lifecycle and supply posture The 1.5KE10CH is listed as Active — Taiwan Semiconductor continues to manufacture this part with no announced end-of-life.","metaTitle":"1.5KE10CH TVS Diode, 1500W, 8.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE10CH bidirectional Zener TVS diode, 1500W peak pulse, 8.1V standoff, AEC-Q101 automotive qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE10","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"9V","Voltage - Clamping (Max) @ Ipp":"15V","Voltage - Reverse Standoff (Typ)":"8.1V","Current - Peak Pulse (10/1000µs)":"105A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2712","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/431552e77c338e767b231e3e0e6aabc1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE10CH/alternatives.json"},"ai":{"faq":[{"question":"What automotive qualification does the 1.5KE10CH carry?","answer":"The 1.5KE10CH is AEC-Q101 qualified, the automotive discrete semiconductor stress-test standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE10CH","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5KE10CH when reusing this data.
