Procurement Notes

Verify the specific ordering suffix when purchasing, as it determines the packing method. Options include standard reels (RF) or green compound variants (RFG). Confirm that the selected part number matches the required voltage tolerance and packaging quantity for your production line requirements.

Selection Notes

Select this component based on the required 2.7 V reference voltage and the 300 mW power dissipation limit. Ensure the operating environment stays within the specified -55 °C to +150 °C junction temperature range. Verify that the 83 Ω impedance meets the circuit's regulation needs.

Part Context

This part belongs to the AZ23C series, which covers a wide Zener voltage range from 2.7 V to 51 V. All devices in this series share the same SOT-23 mechanical footprint and thermal characteristics, allowing for consistent board layout across different voltage requirements.

Replacement Considerations

Cross-reference with other manufacturers offering dual Zener arrays in SOT-23 packages. Ensure replacement parts match the 2.7 V nominal voltage, 300 mW power rating, and 83 Ω impedance specifications.
