At 16.3A peak pulse current, the maximum clamping voltage is 92V. This clamping ceiling is what the protected load actually sees — the part must sit below the downstream circuit's absolute-maximum rating to offer valid protection. ## Standoff and breakdown — the protection window The reverse standoff voltage of 58.1V typical is the working voltage the TVS sees during normal operation without conducting. The minimum breakdown of 64.6V is where the device begins to avalanche and clamp. The 64.6V minimum breakdown sits comfortably above a 48V nominal rail, giving the design engineer headroom against supply variation and ripple. The 58.1V standoff is the typ value; the datasheet specifies the range, so confirm the worst-case standoff at the temperature of interest before committing the part to a 48V rail. ## Where a unidirectional Zener TVS fits This part is listed for general purpose applications and is not rated as power-line protection. It protects downstream circuits from locally-generated or conducted transients on a DC power rail or signal line — not the AC mains entry point, which demands a higher energy-rated varistor or gas-tube at the line side.","metaTitle":"1.5SMC68A TR13 PBFREE TVS Diode, 1500W, 92V Clamp","metaDescription":"Central Semiconductor unidirectional Zener TVS diode, 1500W peak pulse, 58.1V standoff, 64.6V min breakdown, 92V clamp at 16.3A, -65°C to 150°C, DO-214AB SMC","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)":"64.6V","Voltage - Clamping (Max) @ Ipp":"92V","Voltage - Reverse Standoff (Typ)":"58.1V","Current - Peak Pulse (10/1000µs)":"16.3A"}},"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/1.5SMC68A%20TR13%20PBFREE/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/central-semiconductor-corp/1.5SMC68A-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/1.5SMC68A-TR13-PBFREE when reusing this data.
