Surface-mount termination with the typical tin-lead finish supports reflow-profile assembly; the tape-and-reel and cut-tape options cover both production run and prototype quantities. Bidirectional single-channel TVS — when protecting an AC node or a rail where polarity reversal is possible, the bidirectional configuration avoids the forward-conduction asymmetry that a unidirectional device would introduce.","metaTitle":"1.5SMC6.8CA Littelfuse TVS Diode, 10.5V Clamping","metaDescription":"Littelfuse 1.5SMC6.8CA bidirectional TVS diode, 5.8V standoff, 6.45V breakdown, 10.5V clamping at 144.8A, 1500W peak pulse, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Voltage - Breakdown (Min)":"6.45V","Voltage - Clamping (Max) @ Ipp":"10.5V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"144.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/118f1b70ec0f0941665a20e5472af60a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC6.8CA/alternatives.json"},"ai":{"faq":[{"question":"What TVS ratings matter most when specifying this diode?","answer":"The clamping voltage of 10.5V at 144.8A peak pulse tells you the maximum stress the protected circuit sees during a surge. The reverse standoff of 5.8V sets the normal operating ceiling — the part stays off until the transient exceeds the 6.45V breakdown threshold.
