Clamping at 126 V maximum (at Ipp 11.9 A) keeps the downstream rail within the safe operating area of typical 100 V-rated ICs, with a 78 V reverse standoff that leaves margin on a nominal 48 V or 60 V bus. DO-214AA (SMB) surface-mount package — the same footprint as many standard TVS diodes, so a layout already using SMB for other rail protection needs no copper-pattern change.","metaTitle":"Bourns 1.5SMBJ78A-H TVS Diode, 1500W, 78V, AEC-Q101","metaDescription":"Bourns 1.5SMBJ78A-H automotive TVS diode, 1500W peak pulse, 78V reverse standoff, AEC-Q101 qualified.
