UNSPSC 32121707: Silicon controlled rectifier

A four-layer solid state device that controls current.

UNSPSC 32121707 Silicon controlled rectifier (Commodity) shows minimal relevant recent activity in state and local procurement. The six opportunities posted between February and July 2026 that carry this code tag involve elevator maintenance, cold patch asphalt, solenoids, ballasts and capacitors, Schneider electrical components, law enforcement equipment, water treatment facility upgrades, bus parts, transformer replacement, and electric protective devices—none of which are silicon controlled rectifiers (SCRs) or closely related power semiconductor components. The code appears to be applied inconsistently across disparate electrical and mechanical procurement categories, suggesting either taxonomic misalignment in the issuing bodies' systems or that SCR-specific procurement from state and local government does not regularly surface in publicly posted notices.

No recent opportunities specifically solicit silicon controlled rectifiers as discrete components or primary deliverables. Issuers include county departments (Gwinnett County Parks, Hillsborough County), cities (Arlington, Tampa, Austin, Gainesville, Orange County), regional authorities (Sourcewell cooperative), and transit systems, but none frame their solicitations around SCR sourcing. The geographic spread spans Texas, Georgia, Florida, Washington, Minnesota, and California, reflecting general electrical infrastructure procurement across multiple regions rather than concentration in SCR supply. Unless your firm supplies SCRs embedded within larger electrical assemblies or control systems for water treatment, power distribution, or transit applications, this code does not currently present actionable opportunities.
