Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and variant selection. Confirm that the requested part number matches the exact electrical specifications required for the target application. Cross-reference the manufacturer part number with distributor listings to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a 30 V rating and 300 mW power handling capability is required. Ensure the design accommodates the SOT-23 footprint and the specified thermal characteristics. Verify that the 80 Ohm impedance and 100 nA leakage parameters meet the circuit's precision and noise requirements compared to single-diode alternatives.

Part Context

This part belongs to the AZ23C series of Zener diodes from Taiwan Semiconductor. The series offers various voltage options in a compact SOT-23 package. The AZ23C30 RFG specifically provides a 30 V dual common anode configuration, distinguishing it from single diodes or other voltage variants within the same family.

Replacement Considerations

AZ23C30-G3-08 by Vishay Semiconductors is a publicly confirmed substitute with identical 30 V dual common anode specifications and SOT-23 packaging.
