Below that sits the reverse leakage spec, which is the drain on the protected rail during idle. Breakdown triggers at 71.3 V minimum, which is where the TVS snaps into conduction and begins clamping. The spec is stated as a minimum because the part must guarantee turn-on at this level — a 'typical' figure alone would not be a design floor. The clamping voltage of 103 V at the rated peak pulse current is what the downstream load sees during a transient event. At 15 A through the device the clamp is held at 103 V — any higher clamping voltage means more overstress on the protected IC or rail segment. ## 1500 W at 10/1000 µs — what that waveform means This is a slow, energy-dense transient relative to an ESD event, more representative of inductive kick or power-line surge than a human-body discharge. The 1.5 kW figure is the energy the package can absorb once without degradation. At that pulse the peak forward current is 15 A. For a 64 V rail this puts the clamping action at 103 V — the TVS dissipates the difference between the transient peak and the clamp voltage as heat in the sub-millisecond window. The DO-214AB SMC package handles this with a copper heat-spreading tab; thermal resistance to junction is the limiting factor for repetitive events. ## Junction temperature range for bench and field use Rated to 150 °C junction maximum with a -55 °C low end — the upper bound is set by the Zener avalanche mechanism, which becomes less stable as the junction approaches the thermal limit. A design using this part in a sealed enclosure at 85 °C ambient needs to account for the self-heating of the TVS under fault conditions before the junction hits 150 °C.","metaTitle":"1.5SMC75CA M6G — 1500W TVS Zener, 103V Clamping","metaDescription":"Taiwan Semiconductor 1.5SMC75CA M6G bidirectional TVS Zener in DO-214AB SMC, 1500W peak pulse, 64.1V standoff / 71.3V breakdown / 103V clamping.","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":"1.5SMC75","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)":"71.3V","Voltage - Clamping (Max) @ Ipp":"103V","Voltage - Reverse Standoff (Typ)":"64.1V","Current - Peak Pulse (10/1000µs)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC75CA%20M6G/alternatives.json"},"ai":{"faq":[{"question":"What does the 'CA' suffix mean on the 1.5SMC75CA M6G?","answer":"The 'CA' denotes the bidirectional (antiparallel) polarity variant — one channel that clamps both positive and negative transients.
