The 150°C ceiling governs the peak-pulse current derating curve; if the surge duty cycle is high, the design should check the thermal cumulative effect against this limit rather than relying on the peak-pulse headline number alone. ## SMC package and surface-mount integration The DO-214AB (SMC) package is the mid-power TVS form factor — larger than the SMA (DO-214AC) and smaller than the 5 kW parts that use a non-standard outline. Surface-mount orientation means the cathode band must be correctly identified before placement — the diode conducts in the forward direction below the standoff voltage and clamps in the reverse direction above breakdown.","metaTitle":"Diotec 1.5SMCJ70C TVS Diode, 70V, 1.5kW","metaDescription":"1.5SMCJ70C by Diotec Semiconductor — bidirectional TVS diode, 70V standoff, 1.5kW peak pulse, 12A peak pulse current, DO-214AB SMC.","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)":"77.8V","Voltage - Clamping (Max) @ Ipp":"125V","Voltage - Reverse Standoff (Typ)":"70V","Current - Peak Pulse (10/1000µs)":"12A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8068","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ70C/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ70C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ70C when reusing this data.
