Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ordering suffix matches the required AEC-Q101 qualification and reel specifications. Ensure compliance with RoHS directives and check for any specific material categorization requirements relevant to the target application environment.
Selection Notes
Select this component when a precise 3.9 V reference is needed within a compact SOT-23 footprint. Consider the dynamic resistance and leakage characteristics for low-current precision tasks. Verify thermal management capabilities if operating near the upper limits of the specified temperature range.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, offering standardized grading according to the international E24 standard. These devices are designed for general-purpose voltage regulation and clamping duties in consumer and industrial electronics.
Replacement Considerations
Direct replacements must match the 3.9 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit performance remains unchanged during substitution.
