The breakdown voltage floor of 94.4V is where conduction starts, and the 137V clamp is the hard ceiling the load sees during a surge. ## DO-214AA (SMB) surface-mount — board-fit and thermal path The junction operates from -55°C to 150°C, so the board's copper area and via count under the pad must sink the 600W pulse's heat without exceeding the solder joint's temperature limit. Supplied on Tape & Reel (TR) or Cut Tape (CT), the part is compatible with standard pick-and-place assembly. The SMB footprint is shared across the SMBJ family, so a single PCB land pattern serves the full voltage range from 5V to 188V standoff.","metaTitle":"SMBJ85A-13 TVS Diode, 85V Standoff, 600W, DO-214AA","metaDescription":"SMBJ85A-13 unidirectional TVS diode, 85V reverse standoff, 137V clamping, 600W peak pulse power in DO-214AA (SMB) package.
