Tape-and-reel packaging at this body size is compatible with standard SMT pick-and-place; verify the land pattern against the manufacturer footprint drawing before committing to layout since the exposed pad and solder-thermic interface are the dominant thermal path from junction to board copper.","metaTitle":"1.5SMC91A R7G TVS Diode, 1.5kW 125V Clamping","metaDescription":"Unidirectional TVS diode, 77.8V standoff / 86.5V breakdown / 125V clamping at 12.6A peak pulse. 1.5 kW peak pulse power.
