The DO-214AB (SMC) package footprint is the industry-standard outline for 1500W TVS diodes. The cathode tab on the top surface needs a thermal via array to the ground plane — the datasheet's recommended copper area under the tab directly sets the junction-to-ambient thermal resistance for repetitive pulse trains. This is a unidirectional device (one channel), meaning it clamps positive transients above the breakdown voltage while conducting the reverse polarity through the body diode. For a 24V automotive rail that sees reverse-battery events, a series blocking diode or a bidirectional TVS upstream is needed — the 1.5SMC39AHR6G alone does not protect against sustained reverse polarity. The HR6G suffix specifically denotes the AEC-Q101 automotive grade in tape-and-reel packaging for automated assembly.","metaTitle":"1.5SMC39AHR6G TVS Diode, 1500W, 33.3V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC39AHR6G automotive TVS diode, 1500W peak pulse power, 33.3V reverse standoff, AEC-Q101 qualified, DO-214AB SMC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMC","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC39","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)":"37.1V","Voltage - Clamping (Max) @ Ipp":"53.9V","Voltage - Reverse Standoff (Typ)":"33.3V","Current - Peak Pulse (10/1000µs)":"29A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC39AHR6G/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC39AHR6G","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/1.5SMC39AHR6G when reusing this data.
