Engineering FAQ

PACDN004SR is marked Obsolete — how does ZDI assure authenticity?
Obsolete and end-of-life parts carry elevated counterfeit risk, which is exactly why ZDI routes every lot through the full EQuality Process™ — validation, QI-1 and QI-2/camera inspection, RoHS verification, bake and bag-and-tag, and QI-3 final inspection — with source-country supplier vetting and full lot traceability before release.
What are the key specifications of PACDN004SR?
Channels: 4; Standoff Voltage: 5.5 V; Clamping Voltage: 9.5 V @ 1 A.
What package is PACDN004SR supplied in?
PACDN004SR is supplied in the SOT-143 package, surface mount, rated -40°C ~ 85°C.
Can ZDI source PACDN004SR beyond the quantities shown?
Yes — ZD Integrated Circuits specializes in sourcing hard-to-find, obsolete, and excess electronic components through its global network, with counterfeit-avoidance inspection on every lot. Submit an RFQ with your target quantity for availability and pricing.

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

PACDN004SR 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.
