AEC-Q101 qualification and an operating junction temperature range of -55°C to 150°C make it suitable for under-hood or chassis-mounted ECUs that see engine-bay thermal cycling and load-dump events. ## Clamping voltage and surge rating With a minimum breakdown voltage of 48.5V, the device triggers before the protected rail exceeds the 43.6V standoff level. The 70.1V clamping voltage at 22A peak pulse current ensures the downstream silicon sees a peak below its abs-max rating for a 12V or 24V automotive bus. Supplied in tape-and-reel packaging, it suits automated pick-and-place assembly for high-volume automotive modules.","metaTitle":"1.5SMC51CAHM6G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC51CAHM6G bidirectional Zener TVS, 1500W peak pulse, 43.6V standoff, 70.1V clamp, AEC-Q101 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","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC51","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"48.5V","Voltage - Clamping (Max) @ Ipp":"70.1V","Voltage - Reverse Standoff (Typ)":"43.6V","Current - Peak Pulse (10/1000µs)":"22A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC51CAHM6G/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC51CAHM6G","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/1.5SMC51CAHM6G when reusing this data.
