It is designed for general-purpose circuit protection in surface-mount assemblies. The surface-mount footprint is compatible with standard reflow soldering processes. No power line protection is offered — this is a standalone transient suppressor, not a rail-clamp array. ## Lifecycle reality and sourcing Vishay has marked the 1.5SMC350A-/9AT as Obsolete. Sourcing is confirmed per RFQ — quantities are lot-specific and no stock-holding claim is made.","metaTitle":"1.5SMC350A-E3/9AT Vishay Zener TVS, 300V Standoff, DO-214AB","metaDescription":"1.5SMC350A-E3/9AT Vishay Zener TVS diode, 300V reverse standoff, 482V clamp, 1500W peak pulse.
