A 12V ECU input protected by this diode sees the rail held below 16V even during a 100A pulse — well within the typical 36V abs-max of automotive-rated downstream ICs. The 1.5kW peak pulse power rating means the device absorbs a single 10/1000µs surge up to that energy without failing short. In a 12V system with a 0.5Ω source impedance, the available surge energy at 100A is well under 1.5kW, leaving margin for repetitive transients. AEC-Q101 qualification certifies the device for automotive stress levels: temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive discrete semiconductor reliability standard. ## Package and board-fit — DO-201 axial footprint The DO-201AA (DO-27) axial-lead package is a through-hole form factor with 0.052-inch diameter leads. The body length is 9.1mm typical; the anode/cathode banding marks the bidirectional orientation — either lead can be the reference. The axial lead spacing fits standard 0.4-inch hole centers on a prototype board or production PCB. ## Sourcing posture — active production, quoted per RFQ It is sourced through authorized and independent distribution channels; pricing and lead time are confirmed at quote against the BOM quantity.","metaTitle":"1.5KE11CAHB0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE11CAHB0G Zener TVS diode, 1500W peak pulse power, 9.4V standoff, bidirectional, AEC-Q101 automotive grade.","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":"Bulk","Applications":"-","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":"1.5KE11","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"10.5V","Voltage - Clamping (Max) @ Ipp":"15.6V","Voltage - Reverse Standoff (Typ)":"9.4V","Current - Peak Pulse (10/1000µs)":"100A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5369","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE11CAHB0G/alternatives.json"},"ai":{"faq":[{"question":"What automotive qualification does the 1.5KE11CAHB0G carry?","answer":"The 1.5KE11CAHB0G is AEC-Q101 qualified, certifying it for automotive-grade reliability testing including temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive discrete semiconductor standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE11CAHB0G","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/1.5KE11CAHB0G when reusing this data.
