When the line is clean the diode stays off; when a surge hits it turns on in under a nanosecond and clamps the voltage at its datasheet limit, then recovers. The series designation 1.5SMC puts it in the 1.5 kW peak-pulse power class in the DO-214AB (SMC) surface-mount package. ## Standoff, breakdown, clamping — which rating drives the selection The reverse standoff voltage is 13 V — this is the maximum working voltage the diode tolerates without conduction. The minimum breakdown is 14.4 V, so the diode stays high-impedance up to that threshold. For a 12 V rail that sees transients, this means the downstream load never sees more than 21.5 V during a surge event, well within the rating of most downstream ICs. The 69.8 A peak pulse current and the 21.5 V clamping ceiling together set the let-through voltage the protected circuit must survive. ## Junction temperature and the -50 °C to 150 °C window The maximum junction temperature is 150 °C with an operating range down to -50 °C. This is a wider-than-commercial window — suitable for industrial enclosures, outdoor equipment, and power-supply environments where cold startup and thermal cycling are both in-scope. The junction temperature rating constrains how much average power the part dissipates under repeated transients; the datasheet derating curve governs the real-world pulse-frequency limit. ## Package and SMT assembly The DO-214AB (SMC) is a standard 2-pin J-bend surface-mount package — the footprint is compatible across all major TVS diode manufacturers at this rating level. The strip packaging is the reel-tape orientation for automated placement. Tin-lead or pure tin finish is manufacturer-dependent; confirm the finish against the Diotec datasheet before reflow profiling, especially if the assembly is going through a lead-free or mixed process.","metaTitle":"Diotec 1.5SMCJ13A TVS Diode, 1.5kW Peak Pulse","metaDescription":"Diotec 1.5SMCJ13A unidirectional TVS diode in DO-214AB SMC. 13V standoff, 14.4V breakdown, 21.5V clamping at 69.8A peak pulse.","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","Capacitance @ Frequency":"-","Supplier Device Package":"SMC/DO-214AB","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.4V","Voltage - Clamping (Max) @ Ipp":"21.5V","Voltage - Reverse Standoff (Typ)":"13V","Current - Peak Pulse (10/1000µs)":"69.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9158","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ13A/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 1.5SMCJ13A and how is it quoted for volume purchases?","answer":"For volume purchases, request a quote with target quantity and required date — independent distributors typically respond with lot-availability and pricing within one business day."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ13A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ13A when reusing this data.
