At 141 A through the clamping voltage of 35.5 V the part dissipates roughly 5 kW for the duration of the 10/1000 µs waveform — this is the standard automotive surge shape defined in ISO 7637-2 and similar load-dump profiles. The diode's job is not to block the surge but to clamp it and let the upstream supply or protection upstream absorb the energy. Verify the thermal pad land pattern against the Bourns landing pattern drawing; a lifted heel on the cathode tab is the most common field failure mode for surface-mount TVS diodes under repetitive surge stress. ## Automotive grade — what the AEC-Q101 qualification signals AEC-Q101 is the automotive discrete semiconductor stress qualification — it covers temperature cycling, high-temperature reverse bias, power temperature cycling, and mechanical shock/vibration that the part must survive without degradation. For a TVS diode protecting an ECU input or CAN/LIN bus node, this qualification means the clamping characteristic is guaranteed across the automotive temperature band throughout the vehicle design life. In engine-compartment or direct-chassis routing the ambient can reach 125 °C+, leaving 25 °C of junction margin at full surge load.","metaTitle":"Bourns 5.0SMDJ22CA-Q TVS Diode, 22V Standoff, 35.5V Clamping","metaDescription":"Bourns 5.0SMDJ22CA-Q bidirectional TVS diode, 22V standoff, 35.5V clamping, 5 kW peak pulse, AEC-Q101, DO-214AB SMC surface mount.","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","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"24.4V","Voltage - Clamping (Max) @ Ipp":"35.5V","Voltage - Reverse Standoff (Typ)":"22V","Current - Peak Pulse (10/1000µs)":"141A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/01b4635941d863dc2cfd632b255cfd4b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What voltage does 5.0SMDJ22CA-Q actually clamp at under surge?","answer":"The standoff sits at 22 V nominal and breakdown starts at 24.4 V minimum — the gap between 22 V and 35.5 V is the protection window the downstream circuit must tolerate for the duration of the transient event."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/bourns-inc/5.0SMDJ22CA-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/5.0SMDJ22CA-Q when reusing this data.
