The peak pulse rating of 105 A at the standard 10/1000 µs waveform tells you the diode survives a single 1.5 kW surge event without degradation. This waveform — 10 µs rise, 1000 µs fall — approximates the IEC 61000-4-5 ring-wave and some lightning-surge profiles, so the part is suitable for input-stage protection on equipment that must survive mains-adjacent transients. The SMC/DO-214AB package gives enough die-area to dissipate that pulse energy without exceeding the 150 deg C junction limit. ## Where it goes on the board Surface-mount SMC/DO-214AB is the standard package for 1.5 kW unidirectional TVS diodes — the foot print is widely supported and the tab area handles the thermal demand of a single surge event. The -50 to 150 deg C junction temperature range gives headroom for industrial environments where the board ambient can spike — the derating curve in the datasheet tells you how much DC bias current you can run at elevated board temperature before the junction limit becomes the constraint. General-purpose marking means no application-specific qualification — it is the default production grade TVS Zener, not AEC-Q automotive or medical-grade. It covers the majority of PCB input protection roles: power supply rails, signal lines, and secondary protection behind a primary bulk-clamp device. For automotive or industrial safety circuits, confirm the relevant IEC 61000-4-5 test level is met by the specific test setup — the datasheet waveform rating is the reference point.","metaTitle":"1.5SMCJ7.5 TVS Diode, 7.5 V Standoff, 14.3 V Clamping, SMC","metaDescription":"Diotec 1.5SMCJ7.5 unidirectional TVS Zener, 7.5 V standoff, 14.3 V clamping at 105 A peak pulse, 1500 W peak, SMC/DO-214AB, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diotec Semiconductor","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-50°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC/DO-214AB","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"8.3V","Voltage - Clamping (Max) @ Ipp":"14.3V","Voltage - Reverse Standoff (Typ)":"7.5V","Current - Peak Pulse (10/1000µs)":"105A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2415","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5SMCJ7.5 or check stock and pricing?","answer":"Quoted to order against your BOM quantity through independent distribution.
