Procurement Notes
This component has been officially declared obsolete by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or approved replacement parts. Designers must confirm end-of-life notices and transition plans before finalizing procurement strategies for legacy systems.
Selection Notes
Engineers should evaluate alternative components from the same series or compatible pin-outs due to the discontinued status. Selection criteria must include matching Zener voltage, power dissipation limits, and package dimensions to ensure mechanical and electrical compatibility in existing layouts without redesign.
Part Context
The DZ23C16-HE3-18 belongs to the DZ23 series of Zener diode arrays produced by Vishay Semiconductors. This series provides dual-channel solutions in small outline packages, targeting applications where board space is limited. The HE3 suffix indicates Halogen-free and RoHS-compliant construction, aligning with environmental regulations for electronic components.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official manufacturer resources for current cross-reference data or equivalent automotive-grade Zener arrays.
