- Reference voltage generation in control modules
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required AEC-Q101 qualification status. Ensure storage conditions comply with moisture sensitivity level 1 guidelines to prevent package damage during soldering processes.
Selection Notes
Select this component when a precise 4.3 V reference is needed in space-constrained designs. The SOT-23 footprint allows for compact PCB layouts. Verify that the thermal dissipation capabilities on the target board support the specified power ratings under expected ambient temperatures.
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 standardized voltage values graded according to the E24 standard. The HE3_A suffix specifically denotes the automotive-grade variant within the product family.
Replacement Considerations
Direct replacements include other DZ23 series variants with identical voltage ratings but different packaging or qualification levels. Cross-manufacturer equivalents must be evaluated against the specific AEC-Q101 requirements and SOT-23 pinout compatibility.
FAQ
What is the ESD rating for this component?
The device meets AEC-Q101 ESD capability standards, supporting greater than 8 kV via the human body model and greater than 800 V via the machine model.
How does the HE3_A suffix affect the component?
The HE3_A suffix indicates that the component is RoHS-compliant and qualified to the AEC-Q101 automotive reliability standard, distinguishing it from commercial grade versions.
What is the maximum junction temperature?
The maximum junction temperature (Tj) for the DZ23C4V3-HE3_A-08 is 150 °C.
