At 144 V minimum breakdown, the device transitions into conduction; the clamping voltage of 209 V at 7.2 A peak pulse (10/1000 µs waveform) is the ceiling the downstream load never exceeds. That 65 V gap between standoff and clamping is the let-through headroom — a sensitive 130 V rail with tight overvoltage tolerance needs a closer standoff-to-clamp ratio than this part delivers, so check the downstream IC's abs-max rating against 209 V before committing it to a 130 V data or power line. A sub-microsecond ring or ESD zap delivers its energy in a shorter time constant; the TVS will clamp it but the let-through voltage profile differs from the datasheet test condition, so look at the Vc waveform shape in the Diotec curves if the threat includes fast transients. ## Thermal and package — the 150°C junction ceiling In a repetitive-surge environment (cyclone cabinet, AC-line close to the TVS), budget the thermal rise per Diotec's RthJA curves and confirm the PCB copper area under the tab is sufficient. Operating from -50°C to 150°C junction covers the industrial cold-start case and the elevated-ambient hot side, so the part is viable in outdoor enclosures and factory-floor panels that see wide temperature swings. The strip packaging is reel-free loose stock — for high-volume production verify that the tape-and-reel option exists in the Diotec series before planning a fully automated line load. Listed as Active under Diotec Semiconductor. This part carries no power-line-protection certification — the absence of a UL 1449 listing means it cannot be marketed as a per-point-of-entry TVS on an AC line. It is correctly positioned as a board-level transient suppressor for DC rails or signal lines, not as a front-door AC service entrance device.","metaTitle":"Diotec 1.5SMCJ130CA TVS Diode, 130V standoff, 209V clamp","metaDescription":"Diotec 1.5SMCJ130CA Zener TVS diode, 130V standoff, 209V clamp at 7.2A peak pulse, 1.5kW, DO-214AB SMC surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diotec Semiconductor","Type":"Zener","Series":"-","Package":"Strip","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-50°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC/DO-214AB","Voltage - Breakdown (Min)":"144V","Voltage - Clamping (Max) @ Ipp":"209V","Voltage - Reverse Standoff (Typ)":"130V","Current - Peak Pulse (10/1000µs)":"7.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7623","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Diotec provide for 1.5SMCJ130CA?","answer":"Request the Declaration of Conformity and material disclosure from Diotec or your distributor before specifying it into an environmental-regulation-controlled end product such as medical or automotive."},{"question":"What is the closest pin-compatible alternative to 1.5SMCJ130CA in this Circuit Protection family?","answer":"Parts in the same 1.5SMCJ series at adjacent standoff ratings may share the same DO-214AB footprint, but the Vc and Ippm values differ — a substitute requires re-checking the clamping voltage against the downstream load's abs-max rating before a BOM substitution is safe."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ130CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ130CA when reusing this data.
