The 121V clamping voltage is the ceiling the protected node sees; ensure the downstream components have a breakdown rating above this level. The DO-214AA (SMB) package is a standard surface-mount footprint shared across the 1.5SMBJ family. The same land pattern serves the full voltage range, so a BOM swap from a lower-voltage variant to this 75V part does not require a board spin.","metaTitle":"Bourns 1.5SMBJ75A-H TVS Diode, 1500W, 75V, DO-214AA","metaDescription":"Bourns 1.5SMBJ75A-H automotive TVS diode, 1500W peak pulse power, 75V reverse standoff, AEC-Q101 qualified.
