Product details

TVS diode for transient protection — what the P6SMB20AT3 is

The P6SMB20AT3 is a transient-voltage-suppression (TVS) diode from onsemi, part of the P6SMB series. It is designed to clamp overvoltage transients on power or signal lines, protecting downstream components in industrial, telecom, or consumer equipment.

onsemi lists the P6SMB20AT3 as Obsolete. The is marked 'current' in some records, but the productStatus is Obsolete, meaning stock may still exist in distribution channels but replenishment is not available. We quote per RFQ against available inventory — no stock-holding claim, no lead-time promise from the factory.

Frequently asked questions

What is the replacement for P6SMB20AT3?

The natural replacement is an active sibling from the same P6SMB series — for example, a P6SMBxxAT3 variant with the same Cut Tape (CT) package and matching standoff voltage. Check the original BOM for the exact voltage and peak pulse power rating to select the correct substitute.

Where can I buy P6SMB20AT3?

Since the part is Obsolete, it is not available from the manufacturer. We source it through independent distribution and excess-stock channels — quote per RFQ against confirmed inventory. No stock-holding claim; availability confirmed at quote time.
