When a transient drives the line above the 86.5 V minimum breakdown, the device avalanches into conduction and clamps the peak at 125 V. That 125 V clamping ceiling is the stress voltage the downstream load sees during the event — the difference between that ceiling and the load's absolute-maximum rating is your protection margin. ## Thermal and package considerations Junction temperature rating extends to 150°C — the upper bound reflects the diode's ability to absorb transient energy without the junction temperature overshooting the SOA during repeated events. Surface-mount, tape-and-reel packaging suits high-volume assembly. The DO-214AB footprint is widely supported by alternate suppliers in the same series, which matters for BOM de-risk if you want a second source — the 1.5SMC91 base number is the common reference for cross-lookup.","metaTitle":"1.5SMC91A M6G TVS Diode, 125V Clamping, 1500W","metaDescription":"Taiwan Semiconductor 1.5SMC91A M6G unidirectional TVS diode, 77.8V standoff, 86.5V min breakdown, 125V clamping, 1500W peak pulse, DO-214AB SMC, active, quoted","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":"1.5SMC91","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)":"86.5V","Voltage - Clamping (Max) @ Ipp":"125V","Voltage - Reverse Standoff (Typ)":"77.8V","Current - Peak Pulse (10/1000µs)":"12.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC91A%20M6G/alternatives.json"},"ai":{"faq":[{"question":"Where can I source 1.5SMC91A M6G and how do I get a price?","answer":"The part is quoted to order through independent distribution against your BOM quantity."},{"question":"What is the closest pin-compatible alternative in the 1.5SMC series?","answer":"Any 1.5SMC91xx variant with the same DO-214AB SMC package and 91V standoff voltage is the logical first candidate — the base number 1.5SMC91 is the series cross-reference point.
