Automotive, AEC-Q101, 5.0SMDJ-Q Zener TVS diode, 150V standoff, 167V breakdown min, 243V clamping max @ 20.6A, 5000W peak pulse, 1 unidirectional channel, -55°C~150°C TJ, Surface Mount, DO-214AB (SMC), Tape & Reel.","salesMarkdown":"## 150 V standoff — what the clamping window means for your rail The 5.0SMDJ150A-QH: That 243 V ceiling is the figure that protects the downstream semiconductor — the downstream device sees a defined voltage spike, not an unbounded surge. As a unidirectional device, this part handles single-polarity transients only — positive-going spikes on a positive rail. Bidirectional variants of the same series exist for AC-coupled nodes or rails where both polarities can appear. ## 5 kW peak pulse — automotive surge endurance 5000 W peak pulse dissipation at the 10/1000 µs standard automotive surge waveform means this part survives the ISO 7637-2 pulse 2a and similar load-dump events without going into thermal runaway. ## AEC-Q101 — the qualification that opens the automotive BOM AEC-Q101 stress testing covers temperature cycling, high-temperature reverse bias, humidity bias, and surge life — the failure modes that kill a TVS in engine-compartment or outdoor telecom deployments. Specifying a non-AEC-Q101 TVS on an automotive BOM risks a PPAP rejection; the QH suffix on this part signals that Bourns has run the qualification matrix and the data package is available. The listed applications — Automotive and Telecom — reflect the two environments where a 150 V standoff rail most commonly appears: ECU input protection downstream of the battery rail, and telecom distribution frames where the supply bus sits at 48 V nominal with tolerance headroom that can reach 150 V in fault conditions. ## SMC package — surface-mount footprint for high-current clamping The DO-214AB (SMC) package mounts flush to the PCB and requires a generous copper pad under the cathode tab for thermal relief — the datasheet specifies the recommended land pattern for a reason. At 20.6 A peak pulse the clamping thermal event is brief but intense; the board-level heat spreading from that tab determines whether the part survives repeated surges without dry-film delamination. Tape-and-reel packaging is standard for SMC parts run on automated pick-and-place lines — confirm the reel diameter and quantity per reel match your assembly feeder configuration before the first build.","metaTitle":"Bourns 5.0SMDJ150A-QH TVS Diode, 150V Standoff, AEC-Q101","metaDescription":"Bourns 5.0SMDJ150A-QH unidirectional Zener TVS, 150V standoff, 243V clamping @ 20.6A, 5kW peak pulse, AEC-Q101 qualified, SMC package.
