Product details

Obsolete – sourcing last-time buys

No future manufacturing is planned.

Cross-reference within the P6SMB family

The base part number P6SMB points to a broad family of 600 W peak-pulse-power TVS diodes. A P6SMB51A variant in the same SMB package is a direct functional substitute if the suffix (e.g., T3) only indicates packaging code.

Sourcing reality for a discontinued line

Because the P6SMB51AT3 is obsolete, procurement must rely on existing distributor stock or the secondary market. No last-time-buy window remains open from the manufacturer.

Frequently asked questions

How can I order P6SMB51AT3 or check stock?

Submit an RFQ through this page. We source from our multi-distributor network and confirm availability and current pricing at quote time. No stock-holding claim is made here.

Is P6SMB51AT3 obsolete?

Yes, onsemi lists the product status as Obsolete. No further production is scheduled.

What is the replacement for P6SMB51AT3?

A P6SMB51A variant in the same SMB package and voltage rating is the closest functional drop-in. Confirm the suffix (T3) only denotes packaging – the electrical characteristics are shared across the P6SMB51A base part.

Can P6SMB51AT3 be used in SMB package designs?

Yes, the P6SMB51AT3 itself is supplied in the SMB package. Any P6SMB51A variant with the same package footprint will fit the same PCB layout.
