That ceiling — not the standoff — is what the downstream IC or module must survive. A 36 V rail protected by this part sees at most 58.1 V at the moment of the strike; the downstream bus sees a clamped event rather than an open-overvoltage condition. ## Automotive temperature grade and AEC-Q101 The AEC-Q101 qualification means it has passed the automotive stress tests for discrete semiconductors — temperature cycling, humidity bias, and surge characterization — making it acceptable for safety and powertrain-adjacent circuits without a full custom qualification run. ## Active production, quoted to order Bourns lists this part as Active. For new automotive designs the part remains orderable through authorized channels; for legacy ECU repair the same order code is the correct BOM replacement — no footprint or clamp-level change to validate.","metaTitle":"Bourns 5.0SMDJ36A-Q TVS Diode, 36 V, 5 kW","metaDescription":"Bourns 5.0SMDJ36A-Q unidirectional TVS diode, 36 V standoff, 58.1 V clamping, 86.1 A peak pulse, AEC-Q101, DO-214AB SMC, −55 °C to 150 °C junction.","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, 5.0SMDJ-Q","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"5000W (5kW)","Base Product Number":"5.0SMDJ","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"40V","Voltage - Clamping (Max) @ Ipp":"58.1V","Voltage - Reverse Standoff (Typ)":"36V","Current - Peak Pulse (10/1000µs)":"86.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/01b4635941d863dc2cfd632b255cfd4b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/5.0SMDJ36A-Q/alternatives.json"},"ai":{"faq":[{"question":"What type of protection does the 5.0SMDJ36A-Q provide?","answer":"It is a unidirectional Zener-based TVS diode — meaning it clamps positive-going transients relative to ground and does not address negative polarity events.
