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 ## Sourcing reality for a discontinued line Because the P6SMB51AT3 is obsolete, procurement must rely on existing distributor stock or the secondary market.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.","metaTitle":"P6SMB51AT3 onsemi TVS Diode – Obsolete","metaDescription":"P6SMB51AT3 from onsemi is now obsolete.
