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, a Commodity code, describes semiconductor switching and detection components that state and local governments procure as parts within broader electronic equipment and law enforcement systems. Recent solicitations show the code captures embedded components rather than standalone PIN diode sales — jurisdictions buy them as line items within service contracts for equipment maintenance, repair, rental, and replacement. The issuing bodies span school districts and cooperative purchasing vehicles representing multi-jurisdictional law enforcement procurement, reflecting the typical end-use pattern where PIN diodes are specified as needed replacements or repair components rather than standalone inventory items.

Northside Independent School District (San Antonio, Texas) issued IFB 2026118 in September 2026 for electronic equipment parts and repairs, with response due September 24, 2026, replacing an expiring contract and requiring all incumbent vendors to rebid or lose future business. Sourcewell, a Minnesota local government cooperative, issued RFP 061626 in May 2026 for law enforcement equipment to serve participating entities across Washington state (Franklin, Grant, Grays Harbor, Chelan, and Yakima counties) and other jurisdictions nationwide, with proposals due June 16, 2026. The geographic activity spans Texas and the Pacific Northwest, with Sourcewell's multi-state cooperative model extending potential reach across the United States and Canada. PIN diode procurement under this code appears tied to maintenance and support contracts rather than volume component purchasing, limiting standalone procurement signals.
