Procurement Notes
This component is officially designated as End-of-Life (EOL) by Vishay Semiconductors. Procurement should focus on verifying remaining stock availability through authorized distributors or checking for official Product Change Notifications (PCN). Designers are advised to initiate replacement strategies immediately due to the discontinuation status.
Selection Notes
Select this part only if legacy compatibility is required, as it is no longer in active production. Verify that the 56 V Zener voltage and 300 mW power rating meet the specific circuit requirements. Ensure the SOT-23-3 footprint matches the PCB layout constraints. Consider alternative components from the same series with updated lifecycle status for new designs.
Part Context
The DZ23C56-HE3_A-08 belongs to the DZ23 series of dual Zener diodes from Vishay. This series is characterized by its compact SOT-23-3 packaging and automotive-grade reliability. It serves as a dual-channel solution for applications requiring two independent voltage references or clamping functions in a single package.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Vishay's official PCN documents or contact the manufacturer directly for recommended alternatives.
