The 128V reverse standoff voltage is the DC or peak-AC voltage the part can sit across without conducting in normal operation. When a transient exceeds the minimum breakdown voltage of 143V, the device transitions into avalanche and clamps the spike to 207V maximum. That 207V ceiling is the number your downstream MOSFET or controller needs to survive — if its abs-max rating is below that, this TVS alone won't protect it. ## Package and board-fit for the DO-214AB footprint Housed in a DO-214AB (SMC) surface-mount package, also referred to as the SMCJ footprint. The base product number is 1.5SMC150, so the -/9AT suffix identifies the lead-free plating and the reel quantity variant. ## Active production and sourcing posture No power-line protection rating (the spec sheet notes 'Power Line Protection: No'), so this is a signal-rail or low-voltage bus TVS, not a mains-side protector. For a 128V DC bus or a 100V AC rectified rail, it fits; for 240V mains, you need a higher standoff part.","metaTitle":"1.5SMC150A-E3/9AT Vishay 1500W TVS, 128V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC150A-E3/9AT Zener TVS diode, 1500W peak pulse, 128V standoff, 207V clamp, DO-214AB SMC.
