For a 12.8V rail carrying automotive battery voltage (which can swing to 14.4V during charging), the 12.8V standoff provides margin without nuisance clamping. This range also suits telecom outdoor cabinets and industrial equipment where the enclosure sees direct solar load in summer. The part is explicitly listed for telecom applications, which typically involve lightning surge protection per ITU-T K.20/K.21 on line cards and base stations.","metaTitle":"1.5SMC15CAH TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC15CAH automotive-grade bidirectional TVS diode, 1500W peak pulse, 12.8V standoff, 21.2V clamp, AEC-Q101 qualified.","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":"1.5SMC15","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)":"14.3V","Voltage - Clamping (Max) @ Ipp":"21.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"74A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3113","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0e7ce2df7ea2ce992a3377557655f082.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does AEC-Q101 qualification mean for this TVS diode?","answer":"AEC-Q101 is the automotive discrete semiconductor qualification standard. It certifies that the part has passed reliability stress tests including temperature cycling, high-temperature reverse bias, autoclave, and ESD sensitivity — and supports PPAP documentation that OEMs require for production programs. Without this grade, a part cannot be placed on an automotive BOM for a tier-1 supplier."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC15CAH","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/1.5SMC15CAH when reusing this data.
