CDLL828/TR

Single Zener Diodes Overview

The CDLL828/TR is a temperature compensated Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage range of 6.2 to 6.9 volts at a test current of 7.5 mA. The device exhibits a maximum Zener impedance of 15 ohms and a temperature stability coefficient of 0.001 percent per degree Celsius. It operates within an extended temperature range from -65°C to +175°C with a DC power dissipation rating of 500 mW at +50°C. The component utilizes a hermetically sealed glass DO-213AA (MELF) package.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage regulation across wide thermal ranges
• Hermetically sealed glass case construction for environmental protection
• Leadless surface mount MELF package configuration

Single Zener Diodes Applications

• High-reliability surface mount applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as CDI Diodes produces this part number while Microchip Technology distributes it. Confirm that the trailing /TR suffix indicates reel packaging if required for automated assembly processes. Ensure the ordering documentation explicitly references the correct datasheet specifications for the CDLL828 variant to match the intended electrical requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 6.2 to 6.9 volt reference is needed with minimal temperature dependence. The 0.001 percent per degree Celsius coefficient makes it suitable for precision analog designs. Consider the 500 mW power dissipation limit and derating curve for thermal management in enclosed environments.

Single Zener Diodes Part Context

This component belongs to the CDLL821 through CDLL829A series of temperature compensated Zener diodes. These devices share similar hermetic glass construction but vary in nominal voltage and temperature stability coefficients. The CDLL828 specifically targets applications requiring a balance between moderate voltage levels and high thermal stability.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other parts from the same series such as CDLL827 or CDLL829, provided their respective voltage ranges and temperature coefficients align with the circuit requirements.
