Quality & Counterfeit Avoidance

ISO 9001 ERAI Member ESD Certified GIDEP Participant ZDI EQuality Process CAGE Code 1V8K2

ZD Integrated Circuits operates an ISO 9001-certified quality system incorporating JEDEC-standard process-control elements. In an era of global sourcing and internet procurement, standards compliance alone no longer assures component authenticity — so ZDI pioneered a multi-layered counterfeit-avoidance program: supplier analysis at the source-country level, detailed component analysis, defined inspection standards for all incoming devices, and stringent supplier rating and review. These programs let ZDI guarantee the integrity and the source of every component it ships.

Every lot moves through ZDI's EQuality Process™ — validation, QI-1 and QI-2/camera inspection, RoHS verification, bake and bag-and-tag, and QI-3 final inspection — with Quality-Manager disposition before release. Nonconforming material is quarantined; conforming material is warehoused or shipped.

✓Multi-stage EQuality Process™ inspection (QI-1 · QI-2/camera · QI-3)
✓Source-country supplier analysis, rating & review
✓Incoming inspection, RoHS verification, bake, full lot traceability
✓ESD-controlled handling · authentic parts guaranteed

STE-ULN2802A is marked Obsolete. Obsolete and end-of-life parts carry elevated counterfeit risk — exactly why ZDI routes them through the full EQuality Process™ with source-country supplier vetting, inspection, and traceability.
