Automotive, AEC-Q101, 5.0SMDJ-Q Series, bidirectional TVS diode, 85V standoff, 5000W peak pulse, 36.5A peak pulse current, DO-214AB (SMC) surface-mount, -55°C to 150°C junction.","salesMarkdown":"## 5 kW peak pulse in an SMC — what the clamping rating means The 5.0SMDJ85CA-Q is a unidirectional Zener-based transient voltage suppressor — the bidirectional C-variant clamps both polarities of a surge event without needing two diodes in anti-series. Rated 5000 W peak pulse at the 10/1000 µs wave shape, it sits behind the primary power rail and bleeds a fault surge to ground before the downstream circuit sees more than 137 V at the peak 36.5 A current level. The 85 V standoff rating is the working voltage — the part idles off and only conducts when the line overshoots past the 94.4 V minimum breakdown threshold. In automotive 12 V supply domains, a 24 V load-dump profile or a motor coil disconnect puts far more than 85 V on the rail; the TVS clamps that transient and resets once the event clears. Junction temperature is rated to 150 °C with a 94.4 V minimum breakdown at -55 °C cold start — the part is characterised for cold-crank survival in engine-bay environments, not just room-temperature bench testing. ## AEC-Q101 qualification — automotive-grade TVS sourcing context The -Q suffix places this inside the Bourns 5.0SMDJ-Q series, which carries AEC-Q101 automotive qualification — the discrete-semiconductor stress-screen standard that covers temperature cycling, humidity bias, and surge life testing beyond what a commercial TVS sees. Automotive and telecom applications are the listed use cases; the AEC-Q101 badge is the signal that the wafer screening and lot traceability follow the automotive flow rather than the generic consumer flow.","metaTitle":"Bourns 5.0SMDJ85CA-Q TVS Diode, 85V, 5kW","metaDescription":"Bourns 5.0SMDJ85CA-Q bidirectional TVS diode, 85V standoff, 5kW peak pulse, AEC-Q101 qualified for automotive and telecom protection circuits.","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)","Applications":"Automotive, Telecom","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"5000W (5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"94.4V","Voltage - Clamping (Max) @ Ipp":"137V","Voltage - Reverse Standoff (Typ)":"85V","Current - Peak Pulse (10/1000µs)":"36.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/05eb851c9694252cd9eda3a357f31c9b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Bourns 5.0SMDJ85CA-Q's listed type?","answer":"The 5.0SMDJ85CA-Q is classified as a Zener-type TVS diode — it uses Zener avalanche breakdown to clamp overvoltage transients in both directions (bidirectional)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/bourns-inc/5.0SMDJ85CA-Q","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/bourns-inc/5.0SMDJ85CA-Q when reusing this data.
