Engineering FAQ

answers from this part's real data
FQP6N40C 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 quantity and packaging is FQP6N40C in ZDI stock?
ZDI holds 10,000 pcs, packaged as BOXED, date code(s) 1444. Request a quote for confirmed quantity, lead time, and pricing.
What are the key specifications of FQP6N40C?
Fet Type: N-Channel; Technology: MOSFET (Metal Oxide); Drain To Source Voltage (Vdss): 400 V; Current - Continuous Drain (Id) @ 25°C: 6 A; Current - Continuous Drain (Id) @ 100°C: 3.6 A; Current - Pulsed Drain (Idm): 24 A.
What package is FQP6N40C supplied in?
FQP6N40C is supplied in the TO-220-3 package, through hole, rated -55°C ~ 150°C.
Can ZDI source FQP6N40C 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

FQP6N40C 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.
