Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as CDI Diodes manufactures this part family while Microchip Technology distributes it. Confirm that the trailing /TR suffix indicates reel packaging if required for automated assembly processes. Ensure the component meets the necessary environmental compliance standards for the intended deployment environment before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable reference near 6.2 V is required under fluctuating thermal loads. The low temperature coefficient makes it superior to standard Zener diodes for precision applications. Consider the DO-213AA package dimensions for PCB layout constraints and verify that the 500 mW power dissipation rating aligns with the circuit's thermal management capabilities.

Single Zener Diodes Part Context

This component belongs to the CDLL821 through CDLL829A series of temperature compensated Zener diodes. These devices are designed to provide stable reference voltages where standard Zener diodes would exhibit significant drift due to temperature changes. The series utilizes specific doping profiles to achieve near-zero temperature coefficients around the nominal voltage point.
