The unidirectional configuration conducts the surge to ground in the forward direction and clamps the reverse polarity through Zener breakdown. For circuits that already have a reverse-polarity protection diode upstream, the unidirectional part is the standard choice; a bidirectional variant would be needed only if the signal swings below ground. ## Package, mounting and sourcing posture The SMB footprint is a standard JEDEC outline — the same pad layout used by the SMC (DO-214AB) family for higher power ratings, but with a smaller body that saves board area when 1500 W is sufficient.","metaTitle":"Bourns 1.5SMBJ70A-H TVS Diode, 70V Standoff, DO-214AA","metaDescription":"Bourns 1.5SMBJ70A-H automotive TVS diode, 1500W peak pulse power, 70V reverse standoff, AEC-Q101 qualified, DO-214AA SMB package.
