When a transient drives the line above the 7.13 V minimum breakdown threshold, the Zener avalanches and clamps the voltage to a maximum of 11.3 V at peak pulse current. That 11.3 V clamping ceiling is what the downstream load sees during the event — the tighter the clamp, the better the protection for voltage-sensitive circuits. The base product number 1.5SMC7.5 confirms the 7.5 V nominal Zener voltage; the CA suffix denotes the bidirectional polarity variant, so the part clamps both polarities without requiring two unidirectional devices back-to-back. ## SMC package and board assembly context The DO-214AB (SMC) package with surface-mount termination suits pick-and-place assembly at standard SMT speeds. The cathode band on the SMC body marks polarity — on a bidirectional part the band still marks the cathode of the unidirectional reference cell, so orientation matters for the polarity-assignment in the schematic even though the part clamps both directions. ## Junction temperature and deployment envelope Rated to 150 °C maximum junction temperature, the part survives the thermal rise from absorbed surge energy in enclosed or poorly ventilated panels. A 150 °C TJ ceiling means it can sit inside sealed enclosures or near heat sources — an industrial drive cabinet, outdoor cabinet, or junction box — without needing derating at the upper end of the industrial ambient range. Tape-and-reel packaging is the standard format for SMT assembly lines; reel quantities follow the industry standard count, which matters for high-volume panel builds where multiple boards per panel drive the reel-length decision.","metaTitle":"1.5SMC7.5CA M6G — 6.4V TVS Zener, 1500W Peak, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC7.5CA M6G TVS Zener, 6.4V standoff / 7.13V breakdown / 11.3V clamp, 139A peak pulse, DO-214AB SMC surface-mount.","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":"1.5SMC7.5","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)":"7.13V","Voltage - Clamping (Max) @ Ipp":"11.3V","Voltage - Reverse Standoff (Typ)":"6.4V","Current - Peak Pulse (10/1000µs)":"139A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC7.5CA%20M6G/alternatives.json"},"ai":{"faq":[{"question":"What voltage does the 1.5SMC7.5CA clamp at during a transient?","answer":"That clamping voltage — not the standoff or breakdown value — is what the downstream circuit sees during the event; it determines whether your protected load survives."},{"question":"What is the difference between the unidirectional and bidirectional versions of the 1.5SMC7.5?","answer":"The base product number 1.5SMC7.5 is the unidirectional variant; the CA suffix marks the bidirectional.
