For a 100 V rail, that window — roughly 111 V breakdown, 179 V clamping — is the design margin you build your protection budget around. 1500 W at the 10/1000 µs standard is the TVS absorption rating for inductive kick and lightning-surge environments. The 8.4 A peak pulse current at that clamping voltage is the current the diode must conduct while clamping — your upstream source or supply must be capable of delivering that fault current into the TVS without exceeding the standoff voltage. In practice, the diode absorbs the energy and the downstream load sees the clamped 179 V ceiling rather than the raw transient. ## DO-214AB package and the thermal reality on the board The SMC (DO-214AB) package is the standard TVS footprint for this power class — the cathodic tab is the thermal conductor, and the land pattern under that pad sets the thermal resistance to the board copper. Junction temperature is rated to 150°C with a storage floor at -50°C, so the board-level heat sinking matters: if the transient energy is repeated, the tab must shed heat faster than the next event arrives. A single-shot surge at rated energy stays within the thermal capacity; a burst sequence derates the effective rating.","metaTitle":"Diotec 1.5SMCJ100C TVS Diode, 100V, 1.5 kW","metaDescription":"Diotec 1.5SMCJ100C unidirectional TVS diode, 100V standoff, 179V clamping @ 8.4A peak pulse, DO-214AB SMC package, -50°C to 150°C.","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)":"111V","Voltage - Clamping (Max) @ Ipp":"179V","Voltage - Reverse Standoff (Typ)":"100V","Current - Peak Pulse (10/1000µs)":"8.4A"}},"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/1.5SMCJ100C/alternatives.json"},"ai":{"faq":[{"question":"What is the 1.5SMCJ100C used for?","answer":"This is a unidirectional Zener-based TVS (transient voltage suppressor) diode designed to clamp voltage spikes on a 100 V rail. It protects downstream circuitry from surge events — inductive kick, ESD, or lightning-coupled transients — by conducting at its breakdown voltage and clamping the peak to 179 V. The listed application is general purpose, so it appears in power supplies, industrial control, and communication equipment where the 100 V standoff matches the rail being protected."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ100C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ100C when reusing this data.
