The DO-214AB (SMC) package requires a copper pad under the cathode tab sized per the datasheet thermal recommendation — the clamping event dumps a high-energy pulse into the package, and the board-level thermal plane is the primary heat-spreading path. The supplier device package field confirms the standard SMC footprint for footprint-compatible second-source screening. ## Junction temperature and automotive qualification The grade is listed as Automotive, and the AEC-Q101 qualification is the primary compliance signal for automotive customer audits — it supersedes a generic RoHS declaration for chassis and powertrain applications, and the base product number 1.5SMC9.1 identifies the voltage family for cross-referencing to alternative AEC-Q101 suppliers within the same series.","metaTitle":"1.5SMC9.1AHR7G Zener TVS Diode, 1500W Peak, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC9.1AHR7G unidirectional Zener TVS diode, DO-214AB package, 1500W peak pulse, AEC-Q101 qualified for automotive.","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":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC9.1","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"8.65V","Voltage - Clamping (Max) @ Ipp":"13.4V","Voltage - Reverse Standoff (Typ)":"7.78V","Current - Peak Pulse (10/1000µs)":"117A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC9.1AHR7G/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC9.1AHR7G","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/1.5SMC9.1AHR7G when reusing this data.
