It belongs to the Circuit Protection category and is supplied in Cut Tape (CT) packaging. ## 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. ## Sourcing this part today Because the 1.5SMC15AT3 is obsolete, availability is limited to existing distributor or broker inventory. We can source it per your RFQ quantity — confirm the BOM line and we will check our multi-supplier network for available stock. No stock-holding claim or lead-time promise is made here; each quote is confirmed at order time.","metaTitle":"1.5SMC15AT3 onsemi TVS Diode – Obsolete, Cut Tape","metaDescription":"1.5SMC15AT3 from onsemi, Circuit Protection TVS diode.
