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 ## Sourcing posture for obsolete inventory Because the part is obsolete, no new factory orders are accepted.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.","metaTitle":"P6SMB11CAT3 onsemi TVS Diode – Obsolete","metaDescription":"P6SMB11CAT3 from onsemi, part of the P6SMB series.
