Procurement Notes

Verify that the ordering suffix matches the required plating specification. The PBFREE designation indicates lead-free compliant terminals. Confirm the tape and reel quantity aligns with production requirements before finalizing purchase orders. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain solderability upon arrival.

Selection Notes

Select this component when a dual Zener topology with a common anode is required to save board space. The 24 V nominal rating fits standard logic and signal levels. Verify that the 350 mW power dissipation limit accommodates the expected thermal environment. Consider the 0.09 %/°C temperature coefficient for precision applications requiring stable reference voltages across varying operating temperatures.

Part Context

This part belongs to the CMPZDA series of dual common anode Zener diodes from Central Semiconductor. The series spans from 2.4 V to 47 V, offering various voltage options in the same SOT-23 footprint. The CMPZDA24V specifically targets mid-range voltage regulation needs where dual independent cathodes are beneficial for differential signaling or dual-supply decoupling.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult manufacturer cross-reference guides or verify pinout compatibility with alternative dual Zener diodes if sourcing constraints arise.
