The breakdown voltage range starts at 10V min, so the part begins conducting before the rail exceeds the upstream regulator's or load's absolute maximum — a common requirement for 9V DC power inputs in industrial and telecom equipment. The - suffix indicates the standard lead-free / RoHS-compliant finish, which matches the majority of modern assembly flows. ## Junction temperature range and mounting Operating junction temperature spans -65°C to 150°C, covering automotive under-hood, outdoor base stations, and industrial motor-drive cabinets where ambient temperatures can exceed 85°C. The wide range means the 500W peak pulse rating is derated only at the high end, not cut by half at 125°C. Surface-mount DO-214AC (SMA) package — the same footprint as many other 500W TVS diodes, making it a drop-in candidate for existing layouts. The bidirectional single-channel construction protects both polarities of an AC or floating DC line without needing two unidirectional parts back-to-back.","metaTitle":"SMAJ9.0CAE3/TR13 Bidirectional TVS Diode – 500W, 9V Standoff","metaDescription":"Microchip SMAJ9.0CAE3/TR13 Zener TVS diode: 500W peak pulse power, 9V reverse standoff, 15.4V clamp at 32.6A, bidirectional, DO-214AC.","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-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"SMAJ9.0","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AC (SMA)","Voltage - Breakdown (Min)":"10V","Voltage - Clamping (Max) @ Ipp":"15.4V","Voltage - Reverse Standoff (Typ)":"9V","Current - Peak Pulse (10/1000µs)":"32.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7b3ddece4863b4621debe180df56adc8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SMAJ9.0CA and SMAJ9.0CAE3?","answer":"The base part SMAJ9.0CA is the generic bidirectional 9V TVS diode; the - suffix on SMAJ9.0CAE3/TR13 denotes the lead-free / RoHS-compliant finish and tape-and-reel packaging.
