Product details

The 1.5SMC16AT3 is an onsemi transient voltage suppressor from the 1.5SMC series, designed to clamp overvoltage spikes on power rails and signal lines in industrial and telecom equipment.

The product status is marked Obsolete. 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.

Supplied on Tape & Reel, the 1.5SMC16AT3 is a standard SMD package compatible with reflow soldering.

Frequently asked questions

Is the 1.5SMC16AT3 obsolete?

Yes, the 1.5SMC16AT3 is marked Obsolete. onsemi has discontinued production. We can source remaining inventory against your RFQ.

What is the recommended replacement for 1.5SMC16AT3?

The evidence does not list an official onsemi replacement order code. A cross-reference within the 1.5SMC series (same package and voltage class) is the logical starting point — confirm the working voltage and peak pulse power match your application before swapping.
