Procurement Notes

Verify the specific ordering suffix (e.g., RFG) against the manufacturer's datasheet to confirm packaging details such as reel size and halogen-free status. Confirm RoHS compliance and moisture sensitivity classification prior to procurement. Ensure the selected variant matches the required tape and reel specifications for automated placement equipment.

Selection Notes

Select this component when a dual Zener array with a 30 V nominal breakdown is required in a compact SOT-23 footprint. Verify that the 300 mW power dissipation rating and ±5% voltage tolerance align with the circuit requirements. Consider the thermal resistance of 420 °C/W for heat management in dense PCB layouts.

Part Context

The AZ23C30 belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. This series provides standardized dual common anode configurations designed for surface mount technology. The component utilizes a plastic molding compound with UL flammability classification rating 94V-0.

Replacement Considerations

Cross-reference with other manufacturers offering dual common anode Zener arrays in SOT-23 packages. Verify matching electrical parameters including Zener voltage, impedance, and power dissipation before substitution.
