UNSPSC 32111514: PIN diode

A diode with a wide, lightly doped 'near' intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor regions. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts.

UNSPSC 32111514 PIN diode (Commodity) covers discrete semiconductor components procured by state and local governments, though recent solicitation activity under this code shows minimal alignment with the commodity's technical scope. The single recent opportunity tagged to the code—Sourcewell RFP #061626 for Law Enforcement Equipment—is a broad cooperative purchasing vehicle addressing law enforcement gear across Washington state and participating jurisdictions nationwide, with no PIN diodes or semiconductor components identified in the procurement's stated scope. The mismatch suggests either a cataloging error in the opportunity posting or that PIN diodes are incidental components within a larger law enforcement equipment bundle; the RFP itself does not detail component-level specifications. State and local governments typically procure PIN diodes as subsystems or components embedded in detection, sensing, or electronic security equipment rather than as standalone line items, which may explain why discrete semiconductor commodity codes show limited direct solicitation activity in state and local notice systems.

Sourcewell, a Minnesota local government cooperative, issued the only recent opportunity on record, with a June 16, 2026 response deadline and participation from Franklin, Grant, Grays Harbor, Chelan, and Yakima Counties in Washington, along with numerous other jurisdictions across the United States and Canada. Vendors interested in this code should verify directly with Sourcewell's Procurement Portal (https://proportal.sourcewell-mn.gov) and the RFP question-and-answer channel (rfp@sourcewell-mn.gov, 888-894-1930) to clarify whether PIN diode components are explicitly required or referenced in the law enforcement equipment specifications. The cooperative purchasing structure allows any selected vendor to serve thousands of governmental agencies, higher education institutions, K-12 school districts, tribal governments, and nonprofits through the established framework agreement.
