Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., /TR) against the datasheet to confirm packaging type, as bulk and tape-and-reel variants may exist. Ensure the DO-213AA-2 footprint matches the design layout. Confirm RoHS compliance status through official Microchip documentation prior to integration.

Single Zener Diodes Selection Notes

Select this component when a 19 V reference is required in a small surface-mount form factor. Consider the ±20% voltage tolerance for circuit precision requirements. Verify that the thermal management capabilities align with the intended operating environment given the wide temperature range specification.

Single Zener Diodes Part Context

This part belongs to the CDLL52xx series of glass-passivated Zener diodes from Microchip Technology. These devices are characterized by high reliability and stability, often utilized in industrial and automotive electronics where robust performance across extreme temperatures is critical.

Single Zener Diodes Replacement Considerations

Check for direct equivalents such as the CDLL5249/TR variant if reel packaging is required. Cross-reference with other manufacturers offering DO-213AA-2 packaged 19 V Zener diodes, ensuring pinout and electrical specifications match exactly.
