That clamping voltage sits well below the typical 60 V abs-max of a downstream 12 V or 24 V automotive ECU regulator, so a single TVS across the supply input catches load-dump and inductive kick transients before they reach the DC-DC converter. The AEC-Q101 qualification (Grade 1, -55°C to 150°C junction) means this part is production-validated for under-hood and chassis-mounted electronics — the temperature range covers hot-soak under the bonnet and cold-crank at -40°C ambient. For a 24 V truck ECU or a 12 V passenger-car body controller, the 26 V standoff gives enough margin above the nominal rail to avoid false triggering from normal ripple. ## DO-214AA SMB — board-fit and thermal Housed in the DO-214AA (SMB) surface-mount package, the 1.5SMBJ26A mates with the standard SMB footprint. The package is compatible with reflow soldering profiles per JEDEC J-STD-020; MSL is typically Level 1 (no bake required before reflow).","metaTitle":"Bourns 1.5SMBJ26A TVS Diode, 1500W, 26V, DO-214AA","metaDescription":"Bourns 1.5SMBJ26A Zener TVS, 1500W peak pulse, 26V reverse standoff, AEC-Q101 automotive grade.
