Its job is to absorb a voltage spike on the line and clamp it before the downstream circuit sees destructive overstress. Rated 5000W peak pulse at 10/1000 µs — this is the standard telecom and automotive surge waveform, a fast-rise spike that decays over a millisecond. That 5 kW rating tells you it sits on a rail that sees real surge exposure, not just a noise-filtering role. ## Standoff, breakdown, and clamping — what each voltage means Breakdown begins at 8.89 V minimum — above this the Zener junction avalanche-conducts and the part transitions from off to protective clamping. The clamping voltage ceiling is 13.6 V max at the rated peak pulse current of 367.7 A. That 13.6 V is what the downstream IC or module sees at the peak of the surge — pick your downstream absolute-max rating above this, with margin. ## Automotive qualification and thermal margin The series designation Automotive, AEC-Q101, 5.0SMDJ-Q flags this as automotive-grade — AEC-Q101 is the discrete semiconductor stress test standard covering temperature cycling, humidity, mechanical shock, and solder heat resistance. It is the qualification that separates an automotive-qualified TVS from a commercial-spec part for engine-compartment or chassis-domain deployments. Operating junction temperature runs to 150°C — the -55°C cold end covers cold-start and high-altitude conditions; the 150°C top end gives margin above the under-hood ambient peaks a summer grade reaches. Bourns specifies the recommended land pattern — follow it for the thermal pad solder joint integrity the AEC-Q101 board-level thermal cycling test requires. ## Where a 5 kW bidirectional TVS fits Bidirectional, single-channel — it clamps one signal or power rail in both directions. If you have a differential pair needing symmetrical protection, two of these in anti-parallel or a dedicated bi-directional bridge configuration handles it. ## Active lifecycle, sourcing posture Sourced to order per BOM quantity. Tape & Reel packaging matches standard SMT assembly flow.","metaTitle":"5.0SMDJ8.0CA-QH TVS Diode, 8V Standoff, 13.6V Clamp, 5kW","metaDescription":"Bourns 5.0SMDJ8.0CA-QH bidirectional Zener TVS, 8V standoff, 13.6V clamping, 5kW peak pulse, AEC-Q101 qualified for automotive and telecom.","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)":"8.89V","Voltage - Clamping (Max) @ Ipp":"13.6V","Voltage - Reverse Standoff (Typ)":"8V","Current - Peak Pulse (10/1000µs)":"367.7A"}},"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":"Where can I source 5.0SMDJ8.0CA-QH and what are the lead times?","answer":"The part is sourced to order against BOM quantity through independent distribution."},{"question":"What does the Q suffix in 5.0SMDJ8.0CA-QH mean for my design?","answer":"The Q flags this part as part of the 5.0SMDJ-QH series, which carries the Automotive, AEC-Q101 qualification.
