Procurement Notes
Verify the manufacturer part number CMSZDA13V TR PBFREE against official Central Semiconductor documentation to confirm specifications. Ensure compatibility with SOT-323 footprint requirements. Check RoHS compliance status if required by project standards. Confirm lead-free designation matches assembly processes.
Selection Notes
Select this component when a dual Zener array with common anode topology is needed in an SOT-323 package. Verify that the 13 V breakdown voltage aligns with system requirements. Ensure the 275 mW power rating is sufficient for the expected operating conditions. Consider the 40 Ohm impedance for dynamic response needs.
Part Context
This part belongs to the CMSZDA series of dual Zener diode arrays from Central Semiconductor. The series offers various voltage options within the same SOT-323 form factor. The 'TR PBFREE' suffix indicates tape-and-reel packaging and lead-free construction. This specific variant provides a 13 V nominal breakdown voltage.
