Unidirectional configuration (single channel) clamps positive transients to ground; for AC lines or bidirectional protection, a different part from the same series is needed. ## Package and temperature envelope for board integration Tape & Reel packaging is the standard SMD format for pick-and-place; the reel quantity is the procurement unit for volume BOM lines.","metaTitle":"Bourns 1.5SMBJ18A-H TVS Diode, 1500W, AEC-Q101, DO-214AA","metaDescription":"Bourns 1.5SMBJ18A-H unidirectional TVS diode, 1500W peak pulse, 18V reverse standoff, AEC-Q101 automotive qualified.
