Transient energy that drives the line above 6.46V (the minimum breakdown) snaps the device into conduction and the clamping characteristic limits the spike to 10.5V maximum at the 150 A peak pulse rating (10/1000 µs waveform). That 10.5V ceiling is what the downstream circuit sees at the height of the event — it is the number that determines whether the protected IC survives the hit. ## 1.5 kW and 150 A — what the peak ratings mean for board-level protection 1500 W peak pulse power is the product of the clamping voltage and the peak pulse current — it characterises the energy the device can absorb without degradation in the 10/1000 µs window. The 150 A peak pulse current rating tells you the current the clamping path can carry before the device is destroyed; a transient that forces more than 150 A through the TVS at 10.5 V will exceed the 1.5 kW abs-max and damage the part. In practice the source impedance of the transient event sets how much current actually flows — the TVS rating must be above the prospective short-circuit current of the supply line. ## 150 °C junction limit in a standard SMC package The 150 °C maximum junction temperature gives real margin for transient thermal events — the clamping action is self-limiting because the IV characteristic curves upward at high current, so the device self-protects to a degree. No power-line protection designation means this part is optimised for signal-line and rail protection in general-purpose circuits, not for direct AC mains clamping.","metaTitle":"1.5SMC6.8A M6G TVS Diode, 5.8V Standoff, 1.5kW","metaDescription":"1.5SMC6.8A M6G unidirectional TVS diode, 5.8V standoff / 6.46V breakdown / 10.5V clamping, 1.5kW peak pulse, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC6.8","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.46V","Voltage - Clamping (Max) @ Ipp":"10.5V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"150A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC6.8A%20M6G/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 1.5SMC6.8A M6G and how is it quoted?","answer":"Sourced through independent distribution against an RFQ — availability and volume pricing are confirmed at quote time.
