UNSPSC 32111502: Zener diodes

UNSPSC 32111502 Zener diodes (Commodity) does not align with the state and local contract opportunities recently posted under this code. The source records describe electrical protection relays, motor control centers, pump station control panels, elevator maintenance, solenoid assemblies, ballasts and capacitors, and Schneider Electric components—none of which are zener diodes or semiconductor devices. A utility authority in Florida solicited SEL 451 and SEL 751 protection relays for SCADA infrastructure; a county in Florida sought pump station control panels and enclosures compliant with UL 508A standards and NEC requirements; and another Florida county issued an ITB for Schneider brand electrical components for SCADA control systems. The category name and the work actually being procured suggest a taxonomy mismatch rather than active procurement of discrete semiconductor components under this code.

State and local buyers posting under this code span utility authorities, county governments, and municipalities in Florida, Georgia, and Texas, primarily in infrastructure and building operations roles. Geographic concentration appears heaviest in Florida, where Kissimmee Utility Authority, Hillsborough County, Bay County, and the City of Tampa posted electrical equipment and control-system solicitations between May and September 2026. Gwinnett County, Georgia posted an RFQ for ballasts and capacitors in June 2026; Trinity Metro in Tarrant County, Texas sought an IDIQ electrical parts supplier in July 2026. The recent-opportunity block does not support active procurement of zener diodes or similar discrete semiconductors under this Commodity code in the state and local market.
