At 14V typical reverse standoff, it sits just below the 15.6V minimum breakdown — normal 14V rails see only the leakage current; a transient that pushes past 15.6V triggers the clamp and the device absorbs the surge energy. In automotive environments — where ISO 7637-2 load-dump transients can deliver joules into a line — that 1.5kW ceiling is what sets the downstream clamping voltage at 23.2V maximum. The clamping level is what the protected load actually sees; 23.2V is well within the common 28V rated bus ceiling in 12V automotive systems. ## Temperature grade and automotive fit Junction temperature range is -50°C to 150°C — that upper bound is the automotive cabin and under-hood ambient band. A TVS in the engine bay or a junction box mounted near the firewall runs at elevated ambient; the 150°C TJ rating gives headroom against the worst-case ambient before the clamping performance shifts. The \"AQ\" suffix and Automotive applications flag indicate Diotec's automotive qualification flow. No separate AEC-Q101 entry is indexed, but the temperature band and automotive designation signal the grade most 12V ECU input-protection designs require for AEC-Q101 compliance. ## Package, mounting, and what strip packaging means for kitting SMC (DO-214AB) is a surface-mount package with a 3.81 mm body width and a 6.10 mm body length — the typical pick-and-place footprint for mid-power TVS on automotive ECUs. The strip packaging designation means the part ships cut-tape or reel with no formed leads; the kitting lead needs to confirm whether the strip is dry-pack and whether an incoming moisture-sensitivity level check is required before reflow, especially if the part sat in a non-temperature-controlled warehouse.","metaTitle":"Diotec 1.5SMCJ14CA-AQ TVS Diode, 14V, 1.5kW, SMC","metaDescription":"Bidirectional TVS Zener, 14V standoff, 1.5kW peak pulse, automotive-qualified SMC (DO-214AB).
