For a 24V nominal automotive bus that sees 36V load-dump transients, the 42.1V clamp keeps the downstream ICs inside their 60V abs-max rating with margin. DO-214AA (SMB) surface-mount package — the same footprint as standard SMB diodes. No power line protection feature (the part is a pure transient suppressor, not a filter). Single bidirectional channel replaces two unidirectional TVS diodes in anti-series for bipolar rails. ## Active lifecycle, automotive compliance AEC-Q101 qualification is the key authority signal for automotive procurement. The part carries the standard Bourns 1.5SMBJ series base number, so datasheet and SPICE models are available from the manufacturer.","metaTitle":"Bourns 1.5SMBJ26CA-H TVS Diode, 1500W, 26V, AEC-Q101","metaDescription":"Bourns 1.5SMBJ26CA-H bidirectional TVS diode, 1500W peak pulse power, 26V reverse standoff, AEC-Q101 automotive grade.
