TVS diode in the P6SMB family – what you need to know
The P6SMB39AT3 is a transient voltage suppression diode from onsemi's P6SMB series, designed to clamp overvoltage spikes on power and signal lines. It is supplied in Cut Tape (CT) packaging.
Obsolete – planning your next move
onsemi lists the P6SMB39AT3 as Obsolete, meaning the manufacturer has discontinued production and no further orders are accepted. For existing BOM lines, you will need to secure remaining inventory or identify a drop-in replacement from the same P6SMB family or a comparable TVS series.
Sourcing through independent channels
Because the part is obsolete, new stock is not available from franchised distributors. We can source the P6SMB39AT3 through our independent supply network — quantities are verified and quoted per RFQ.
