Product details

Device identity and family lineage

The P6SMB11CAT3 is a TVS diode from onsemi, part of the P6SMB series — a 600 W peak pulse power family commonly used for transient voltage suppression on low-voltage supply rails and signal lines.

Obsolete — planning the BOM transition

onsemi lists the P6SMB11CAT3 as Obsolete. For sustainment programs, this means the last-time-buy window has closed; any remaining stock is what is available through independent distribution. The base product number P6SMB ties this part to a well-documented TVS family, so parametric cross-referencing to a non-obsolete sibling or a second-source equivalent is straightforward for the design engineer.

Sourcing posture for obsolete inventory

Because the part is obsolete, no new factory orders are accepted. Availability is limited to existing distributor and broker stock.

Frequently asked questions

Is P6SMB11CAT3 obsolete?

Yes, onsemi lists the P6SMB11CAT3 as Obsolete. No further production is planned. Any available units are from existing stock in the distribution channel.

What is the replacement for P6SMB11CAT3?

The evidence does not list an official onsemi replacement. For a form-fit-function substitute, cross-reference the P6SMB series parametric table — look for a TVS diode with the same reverse standoff voltage, clamping voltage, and 600 W peak pulse power rating in the same DO-214AA (SMB) package.

Where can I buy P6SMB11CAT3?

We source the P6SMB11CAT3 through independent distribution and broker channels. Submit an RFQ with your target quantity and we will confirm availability and pricing at quote time.
