The clamping voltage at that current is 25.5 V max, so downstream silicon rated for 30 V or higher survives the event. The bidirectional channel handles both positive and negative surges in one package — useful on AC-coupled signal lines or on DC buses where reverse-polarity faults are possible. The breakdown voltage range starts at 17.1 V min, so the device does not conduct at the 15.3 V standoff level; it stays invisible to the circuit until a transient pushes the rail above that threshold. ## Automotive-grade screening and temperature envelope The 150°C TJ ceiling is the absolute maximum — derate the peak pulse power above 25°C per the manufacturer's curve. The DO-214AB (SMC) package is the standard footprint for 1500 W TVS diodes in surface-mount assembly. The copper pad area under the cathode tab couples the die to the board copper for thermal spreading during the surge. The tape-and-reel packaging is compatible with standard pick-and-place lines. ## Sourcing and compliance status The base product number is 1.5SMC18, which covers the full voltage variant family in the 1.5SMC series. The suffix CA denotes bidirectional, HM6G is the automotive-grade packaging code. The part carries AEC-Q101 qualification and is RoHS-compliant per Taiwan Semiconductor's standard compliance documentation.","metaTitle":"1.5SMC18CAHM6G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"1.5SMC18CAHM6G bidirectional Zener TVS from Taiwan Semiconductor, 1500W peak pulse, 15.3V standoff, 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":"1.5SMC","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":"1.5SMC18","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)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.5V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC18CAHM6G","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/1.5SMC18CAHM6G when reusing this data.
