Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel quantity. Confirm RoHS compliance status and ensure the component meets the specific thermal management requirements for the target application environment before finalizing procurement orders.

Selection Notes

Select this part when a dual common cathode arrangement is needed within a compact SOT-23 footprint. Ensure the design accounts for the 300 mW power dissipation limit on standard FR-4 substrates and verify that the 13 V breakdown voltage aligns with the system's reference or clamping thresholds.

Part Context

This component 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, providing designers with standardized options for precision voltage regulation tasks across diverse industrial and consumer electronics applications.

Replacement Considerations

Check for DZ23C13-HE3_A variants if AEC-Q101 automotive qualification is required. Verify pinout compatibility and electrical parameters against other SOT-23 dual Zener arrays from different manufacturers before substitution.
