Obsolete status and what it means for your BOM
onsemi lists the 1.5SMC15AT3 as Obsolete. This means the manufacturer no longer produces the part, and no future orders will be accepted from the factory. For a BOM that currently uses this part, you should identify a drop-in replacement or alternate TVS diode with similar clamping characteristics before your existing stock runs out.
