Procurement Notes

Verify the specific ordering suffix R1 indicates Tape and Reel packing on a 7-inch reel according to official documentation. Confirm the version code matches the required environmental compliance standards before procurement. Ensure the component lot number is recorded for tracking purposes as per manufacturer guidelines.

Selection Notes

Select this component when a dual Zener solution with a common cathode topology is required. The 43 V nominal voltage and 300 mW power rating define its operational limits. Verify that the 100 Ω maximum Zener impedance meets the circuit requirements for dynamic performance.

Part Context

This part belongs to the DZ23C2V4 series, which covers Zener voltages from 2.4 V to 51 V. The series utilizes a planar die construction and is housed in an SOT-23 package. Alternative configurations such as common anode styles are available in the AZ series from the same manufacturer.

Replacement Considerations

Cross-reference with other dual Zener diodes in the SOT-23-3 package. Verify matching electrical parameters including Zener voltage tolerance, impedance, and power dissipation ratings to ensure functional compatibility.
