At that rating, the 14.6A peak pulse current flows through the diode during the event, and the clamping voltage of 103V reflects the dynamic resistance under surge conditions, not a steady-state condition. ## DO-214AB SMC — where it lands on the board The DO-214AB (SMC) is a common medium-power TVS footprint — its claw-style terminations sit on a copper pad that must handle the diode's thermal rise under surge. The exposed die attach tab under the body conducts heat to the board pad; for repeated surge events the board-level thermal design matters more than the die itself. Delivered in tape-and-reel (TR13) — the SMC is a standard pick-and-place package for automated assembly, compatible with most reel feeders at 330mm tape diameter. No through-hole reflow constraints; surface-mount profile follows standard lead-free reflow. ## Wide junction temperature — suitability for demanding environments For a general-purpose TVS in an industrial control or power-supply input stage, that thermal envelope covers most closed-panel environments.","metaTitle":"1.5SMC75A TR13 PBFREE Zener TVS Diode, DO-214AB SMC, 64.1V","metaDescription":"Central Semiconductor unidirectional TVS Zener in DO-214AB SMC, 64.1V standoff, 71.3V min breakdown, 103V clamping at 14.6A peak pulse. 1500W peak surge rating.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Central Semiconductor Corp","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","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":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"71.3V","Voltage - Clamping (Max) @ Ipp":"103V","Voltage - Reverse Standoff (Typ)":"64.1V","Current - Peak Pulse (10/1000µs)":"14.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2951","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9191afc3e92f03eb3c6f3d25e0a397c7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC75A%20TR13%20PBFREE/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between the standoff voltage and the clamping voltage on a TVS diode like 1.5SMC75A?","answer":"The standoff voltage (64.1V) is the maximum working voltage the circuit can run at without the diode conducting; the clamping voltage (103V max) is the voltage ceiling the diode enforces during a transient event — the downstream circuitry must survive 103V for the duration of the surge, which is why the clamping spec, not the standoff, determines what the protected load actually sees."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/central-semiconductor-corp/1.5SMC75A-TR13-PBFREE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/central-semiconductor-corp/1.5SMC75A-TR13-PBFREE when reusing this data.
