Procurement Notes
Verify that the ordering suffix matches the required reel size and minimum order quantity. Confirm RoHS compliance status and ensure the component meets specific environmental requirements for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when a 7.5 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Ensure the application current does not exceed the 5 mA test current specification to maintain accurate voltage regulation and prevent thermal issues.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages according to the E24 standard, providing designers with standardized options for various voltage regulation needs in consumer and industrial electronics.
Replacement Considerations
Direct replacements must match the 7.5 V nominal voltage, SOT-23 package, and ±5 % tolerance. Verify dynamic resistance and leakage current specifications to ensure equivalent performance in the target circuit design.
