That means onsemi no longer manufactures this exact order code. If you're repairing a board that has one, you can still source it through surplus or distributor inventory — we can quote against your BOM quantity. For new designs or production runs, you'll need to qualify a replacement. ## Package and handling note Supplied on Tape & Reel, the 1.5SMC16AT3 is a standard SMD package compatible with reflow soldering. No special handling beyond normal MSL precautions — but always verify the reel orientation for your feeder before committing a full reel to the line.","metaTitle":"1.5SMC16AT3 onsemi TVS Diode – Obsolete","metaDescription":"1.5SMC16AT3 onsemi Circuit Protection TVS, Tape & Reel.
