The 56.7V minimum breakdown is where avalanche starts; the actual breakdown sits between 56.7V and the clamp at 82.4V. At the 18.2A peak pulse current the clamp holds at 82.4V max — that is the voltage the protected IC sees during the transient. For a 60V-rated downstream MOSFET this gives 27V of headroom; for a 75V-rated part the margin is wider still. Bidirectional construction means one device clamps both polarities — no need for two series diodes or a bridge on an AC-coupled signal line or a bipolar supply rail. ## Active production, quoted per RFQ The lifecycle status is Active — Diodes Incorporated continues to manufacture this part.","metaTitle":"SMCJ51CAQ-13-F TVS Diode, 51V, 1500W, DO-214AB, AEC-Q101","metaDescription":"SMCJ51CAQ-13-F bidirectional Zener TVS diode, 51V reverse standoff, 1500W peak pulse power, AEC-Q101 qualified, DO-214AB SMC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Voltage - Breakdown (Min)":"56.7V","Voltage - Clamping (Max) @ Ipp":"82.4V","Voltage - Reverse Standoff (Typ)":"51V","Current - Peak Pulse (10/1000µs)":"18.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2941","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a7bf25a78de51cddef331c6d49312185.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the 51V reverse standoff rating mean for a 48V bus?","answer":"The 51V reverse standoff voltage is the maximum DC voltage the TVS blocks without conducting leakage current. A 48V nominal bus sits 3V below this threshold, so the TVS stays off during normal operation.
