Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm tape-and-reel packaging dimensions and minimum order quantities. Ensure that the HE3 designation aligns with required RoHS compliance standards for the target assembly process.
Selection Notes
Select this component when a 3.0 V reference is required in an SOT-23 footprint. Confirm that the 95 Ω dynamic impedance meets the circuit requirements. Verify thermal dissipation limits based on the PCB copper area and ambient operating conditions.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades according to the E24 standard, all packaged in the compact SOT-23 form factor suitable for space-constrained designs.
Replacement Considerations
Cross-reference with other Vishay DZ23 series variants or equivalent AEC-Q101 qualified Zener diodes in SOT-23 packages. Verify pinout compatibility and ensure replacement parts meet the same electrical tolerances and thermal ratings.
