For a 5 V rail this gives roughly 2:1 headroom in normal mode and clamps the transient well below the withstand rating of downstream semiconductor stages. ## DO-214AB SMC package for surface-mount board assembly The DO-214AB (SMC) package is the standard pick-and-place SMC footprint — the cathode band marks orientation on the reel, and the wide metal tab under the body handles the thermal path from junction to board copper. Tape-and-reel packaging keeps it compatible with standard SMT assembly flow without any special tray or dry-pack requirement for most humidity-sensitive levels. The 1.5SMC series is the general-purpose unipolar/bidirectional TVS family; this single bidirectional channel clamps line-to-line or line-to-ground overvoltage in power rails, signal interfaces, and control lines. It is explicitly listed as not a power-line protection device — it protects the semiconductor side of the interface, not the AC mains or three-phase bus. For a board-level design the standoff voltage sets the rail you can protect; the peak pulse current and clamping voltage define how much surge energy the downstream ICs never see.","metaTitle":"1.5SMC6.8CA M6G Zener TVS Diode, 1500W Peak Pulse","metaDescription":"Taiwan Semiconductor 1.5SMC6.8CA M6G, bidirectional Zener TVS, 5.8V standoff, 6.46V breakdown, 10.5V clamping, DO-214AB SMC.

Once a surge raises the rail above the minimum breakdown (6.46 V), the Zener channel turns on, and the clamping voltage (10.5 V max at 150 A peak) is what appears at the load during the transient event — the lower the clamping voltage relative to the downstream IC abs-max, the better the protection margin."},{"question":"What is the closest alternative to 1.5SMC6.8CA M6G in this TVS family?","answer":"The base product number 1.5SMC6.8 refers to the 6.8 V nominal Zener voltage in the 1.5SMC series; the CA suffix indicates the bidirectional bidirectional construction and tighter voltage tolerance. Other 1.5SMC family members with different nominal Zener voltages share the same DO-214AB SMC footprint and are pin-compatible within the series, but the standoff, breakdown, and clamping values shift proportionally with the Zener voltage — confirm the rail voltage and protection target when selecting a family member."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC6.8CA-M6G","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/1.5SMC6.8CA-M6G when reusing this data.
