Its 7.5V reverse standoff voltage makes it a direct fit for protecting 5V and 3.3V logic rails, sensor supplies, or general-purpose DC buses where the normal operating voltage stays under 7.5V. The 8.33V minimum breakdown voltage gives a clean clamping threshold before the 14.3V maximum clamp at 104.9A peak pulse current. ## Clamping voltage and pulse current At the 1500W peak pulse power level, the device clamps at 14.3V maximum while conducting 104.9A. That clamp voltage is the ceiling the protected circuit sees — a downstream 5V rail with a 6.5V absolute max input will survive this transient, but the margin is tight. For a 3.3V rail, a lower-voltage TVS in the same SMCJ family would be a better fit. Surface-mount DO-214AB (SMC) package, unidirectional polarity.","metaTitle":"SMCJ7.5E3/TR13 TVS Diode – 1500W, 7.5V, DO-214AB, Active","metaDescription":"Microchip SMCJ7.5E3/TR13 Zener TVS: 1500W peak pulse, 7.5V reverse standoff, DO-214AB, -65°C to 150°C, unidirectional, Active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"SMCJ7.5","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"8.33V","Voltage - Clamping (Max) @ Ipp":"14.3V","Voltage - Reverse Standoff (Typ)":"7.5V","Current - Peak Pulse (10/1000µs)":"104.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5550","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to SMCJ7.5E3/TR13?","answer":"Within the same SMCJ family, the SMCJ7.5A (unidirectional, 1500W, 7.5V standoff) is a direct functional equivalent from Microchip.
