Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR PBFREE' to confirm tape-and-reel packaging and lead-free compliance. Confirm the manufacturer is Central Semiconductor Corp, as part numbers may be shared across distributors. Check for RoHS3 certification status if environmental compliance is required for your assembly process. Ensure the SOD-80 footprint matches your PCB design constraints before ordering.

Single Zener Diodes Selection Notes

Select this component when a 27 V Zener voltage is required in a surface-mount MINI-MELF package. The 500 mW power rating suits moderate current applications where thermal management is feasible. Compare the 41 Ohm impedance against circuit requirements for regulation accuracy. Consider the wide operating temperature range for environments subject to significant thermal fluctuations.

Single Zener Diodes Part Context

This component belongs to the CLL52xxB series of Zener diodes from Central Semiconductor Corp. These devices are characterized by their robust construction and suitability for general-purpose voltage regulation tasks. The series offers various voltage options within the same physical package, simplifying inventory management for designs requiring multiple reference voltages.

Single Zener Diodes Replacement Considerations
