The 1500W peak pulse rating at the standard 10/1000 µs waveform sets this well above the common 500W parts in the same SMC package, meaning it handles higher-energy transients without derating to a lower class of protection. The standoff voltage of 58 V typ defines the working DC bias the line can sit at continuously without the TVS conducting. If a surge drives the line above that, the device breaks down at 64.4V minimum and clamps the peak pulse current of 16 A to a maximum of 93.6 V — that clamping ceiling is what the protected circuit actually sees at the defined current. ## Junction thermal margin and deployment environment Junction temperature is rated from -50°C to 150°C — the upper end gives meaningful margin against the self-heating pulse during clamping events, so the part is viable in enclosed industrial enclosures without active thermal management. General-purpose application rating means it is not screened to automotive AEC-Q101 or defence JAN specs, but for industrial and commercial boards the temperature band is sufficient. The DO-214AB (SMC) package is the standard surface-mount footprint for this power class — the cathodic tab on the wide side maps to the protection rail, and the matching land pattern seats to the board without special keep-out. No power-line protection flag in the listing means this is a board-level protection device, not a mains-supply TVS per IEC 62368 or similar.","metaTitle":"Diotec 1.5SMCJ58A TVS Diode, 1.5kW Peak, 58V Standoff","metaDescription":"Diotec 1.5SMCJ58A unidirectional Zener TVS diode, 1500W peak pulse, 58V standoff, 93.6V clamping, -50 to 150°C TJ, DO-214AB SMC, active.","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)":"64.4V","Voltage - Clamping (Max) @ Ipp":"93.6V","Voltage - Reverse Standoff (Typ)":"58V","Current - Peak Pulse (10/1000µs)":"16A"}},"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/1.5SMCJ58A/alternatives.json"},"ai":{"faq":[{"question":"What is 1.5SMCJ58A used for?","answer":"This Zener TVS protects board-level nodes against transient voltage spikes — it sits across a signal or low-power rail at its standoff voltage and clamps any surge above 64.4V to 93.6V maximum, safeguarding downstream ICs in industrial control, power supplies, and communication equipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diotec-semiconductor/1.5SMCJ58A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diotec-semiconductor/1.5SMCJ58A when reusing this data.
