Product Details
DS2401AZ+ - 1-Wire Silicon Serial Number
DS2401AZ+ from Analog Devices / Maxim Integrated is a factory-programmed silicon serial-number IC with a globally unique 64-bit ROM in a three-lead SOT-223 tube package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS2401 adds a unique electronic registration number to a board or subsystem using a single data contact plus ground. The 64-bit ROM contains a family code, unique serial number and CRC.
Key Advantages
Adds a permanent factory-lasered identifier without programming inventory.
Uses the 1-Wire protocol and draws no standby power from a dedicated supply.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Silicon serial number
1-Wire, up to 16.3 kbps
2.8 V to 6.0 V; -40 C to +85 C
TO-261-4, TO-261AA
Package & Footprint
This ordering code uses the TO-261-4, TO-261AA package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Replacement Considerations
DS2401AP+ is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Analog Devices identifies both as DS2401A-family serial-number devices, but the linked 6-TSOC version has a different footprint and pin arrangement.
Applications
Provides a permanent unique identifier for manufacturing and service records.
Lets a controller enumerate and identify hardware over a 1-Wire connection.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
Silicon serial number
What package is used?
TO-261-4, TO-261AA
Can the related part be substituted directly?
No. Validate all electrical, mechanical and configuration differences first.
Is the package image ready?
No. The registered package JPG is currently missing.
Engineering Notice
Use the latest manufacturer documentation for schematic, PCB, thermal and production approval. Distributor attributes are useful for sourcing but do not replace the official data sheet.
