The 58.1V reverse standoff is the working voltage — the diode remains off and draws only leakage current under normal bus conditions. 1500W peak pulse power means the part survives a single 10/1000 µs surge at rated amplitude without degradation — this is the standard IEC 61000-4-5 surge immunity test waveform. The bidirectional polarity handles symmetric transient events on a single polarity rail without requiring two opposite-polarity devices. ## Automotive temperature grade and under-hood deployment AEC-Q101 qualification means it has passed the temperature cycling, surge life, and humidity bias sequences that automotive boards require for safety and powertrain domains. ## Telecom rail protection in a telecom application class Listed with Telecom applications — DC power rails in telecom equipment run at 48V nominal, and the 58.1V standoff sits comfortably above the 54V float-charge ceiling. The DO-214AB SMC footprint is the industry-standard SMB footprint for TVS devices on 48V bus protection cards; it mates with the same pad geometry as SMB TVS parts from other manufacturers.","metaTitle":"1.5SMC68CAH — AEC-Q101 TVS Zener, 58.1V standoff","metaDescription":"AEC-Q101-qualified unidirectional TVS Zener from Taiwan Semiconductor. 58.1V standoff, 1500W peak pulse, 17A peak pulse current.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"Telecom","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC68","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"64.6V","Voltage - Clamping (Max) @ Ipp":"92V","Voltage - Reverse Standoff (Typ)":"58.1V","Current - Peak Pulse (10/1000µs)":"17A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3113","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a98cbdee7453c45b34d123c719aa0744.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC68CAH/alternatives.json"},"ai":{"faq":[{"question":"What does AEC-Q101 qualification mean for a TVS diode?","answer":"AEC-Q101 is the automotive stress test for discrete semiconductors — it covers surge life, temperature cycling, and humidity bias."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC68CAH","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5SMC68CAH when reusing this data.
