Procurement Notes
Verify the specific suffix 'TR PBFREE' to confirm tape-and-reel packaging and lead-free compliance. Ensure the sourcing channel provides valid RoHS documentation. Confirm the manufacturer is Central Semiconductor Corp to avoid counterfeit components. Check for any automotive or industrial grade variants if operating conditions require extended temperature ranges beyond standard specifications.
Selection Notes
Select this component when a dual zener solution with a common anode is required in a small footprint. The SOT-23 package suits space-constrained designs. The 3.1V to 3.5V range fits low-voltage regulation needs. Consider the 350mW power rating for thermal management. Verify compatibility with existing PCB land patterns for SOT-23 packages during the design phase.
Part Context
This part belongs to the zener diode array category from Central Semiconductor Corp. It complements single-channel zener diodes by offering dual functionality in one package. The series includes various voltage options and configurations. The CMPZDA3V3 specifically targets applications needing paired regulation elements without increasing board area significantly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other manufacturers' dual zener arrays in SOT-23 packages only after verifying electrical parameter equivalence.
