Breakdown occurs at a minimum of 485V, providing a 51V margin before the avalanche region. ## DO-214AB SMC package — board-fit and thermal path Housed in the standard DO-214AB (SMC) surface-mount package, also designated as the SMCJ supplier device package. The footprint is shared across the 1.5SMC series, so a single PCB land pattern accepts the full voltage range within the family. The tape-and-reel packaging (TR) supports automated pick-and-place assembly.","metaTitle":"Vishay 1.5SMC510A-E3/9AT TransZorb TVS, 1.5kW, 698V Clamp","metaDescription":"Vishay 1.5SMC510A-E3/9AT TransZorb TVS diode, 1500W peak pulse, 434V standoff, 698V clamp.
