That clamping voltage is the number your downstream IC's abs-max rating must survive — a 24 V-rated ECU supply has margin; a 16 V-rated sensor rail does not. The -55 to 150 °C junction temperature range covers the full under-hood ambient envelope with derating headroom — at 125 °C case temperature the 1500 W rating derates to roughly 60 %, so the actual transient energy the device can absorb drops in a hot engine bay. Design the clamp current budget at the worst-case operating temperature, not at 25 °C. ## Package fit and footprint DO-214AA (SMB) — same footprint as the rest of the 1.5SMBJ series. The cathode band aligns with the package marking; the anode is the tab. Solder pad geometry per the Bourns recommended land pattern: a 2.0 mm wide pad on the cathode side with a thermal via under the tab pulls heat into the inner-layer copper pour. Reflow profile follows standard JEDEC J-STD-020 for a moisture sensitivity level (MSL) 1 device — no bake required before reflow if the shelf life in the sealed bag is unbroken.","metaTitle":"Bourns 1.5SMBJ14A-H TVS Diode, 1500W, 14V, DO-214AA","metaDescription":"Bourns 1.5SMBJ14A-H AEC-Q101 automotive TVS, 1500W peak pulse, 14V reverse standoff, DO-214AA (SMB).

The closest unidirectional 14 V alternative is the standard (non-automotive) 1.5SMBJ14A — same breakdown and clamping voltages, same package, but without AEC-Q101 qualification. If the BOM requires automotive-grade screening, the -H suffix part is the correct choice."},{"question":"What compliance documentation does Bourns provide for the 1.5SMBJ14A-H?","answer":"Bourns supplies RoHS and REACH compliance declarations with the standard product documentation. The AEC-Q101 qualification test report is available from Bourns on request for PPAP submissions.
