Automotive, AEC-Q101, 1.5SMBJ series bidirectional TVS diode, 1500W peak pulse power, 33V reverse standoff, 36.7V breakdown, 53.3V clamping, DO-214AA (SMB) package, Tape & Reel.","salesMarkdown":"## What the 1500W rating means on a 33V rail The 1.5SMBJ33CA-H: On a 33V nominal rail (reverse standoff voltage 33V), it clamps transients to 53.3V maximum, shunting up to 28.2A peak pulse current. That 1500W rating means it absorbs high-energy surges like automotive load dump or lightning-induced spikes without failing — not just ESD-level events. ## Automotive grade and temperature range If you are building an ECU, BMS, or ADAS sensor module, this is the temperature grade you need. ## Package and field replacement The bidirectional configuration means a single device protects both polarities, reducing component count on the board. Polarity orientation is not an issue; it clips the same either way.","metaTitle":"Bourns 1.5SMBJ33CA-H TVS Diode, 1500W, 33V, DO-214AA","metaDescription":"Bourns 1.5SMBJ33CA-H bidirectional TVS diode, 1500W peak pulse power, 33V standoff, AEC-Q101 automotive grade, DO-214AA (SMB) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Bourns Inc.","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMBJ","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMBJ","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Voltage - Breakdown (Min)":"36.7V","Voltage - Clamping (Max) @ Ipp":"53.3V","Voltage - Reverse Standoff (Typ)":"33V","Current - Peak Pulse (10/1000µs)":"28.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2743","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee1fb175d38950cd5a23672129674f6e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMBJ33CA-H/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Bourns provide for 1.5SMBJ33CA-H?","answer":"The part is AEC-Q101 qualified for automotive applications.
