CDLL5270D/TR

Single Zener Diodes Overview

The CDLL5270D/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a nominal Zener voltage of 91 V with a tolerance of ±1%. The device is housed in a DO-213AA (SOD-80) package and supports a maximum operating temperature of 175°C. Key electrical characteristics include a reverse leakage current of 100 nA at 69 V and a forward voltage of 1.1 V at 200 mA. The component exhibits a maximum Zener impedance of 400 Ohms and is classified under ECCN EAR99.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 91 V level
• Supports high-temperature operation up to 175°C
• Utilizes a compact surface-mount DO-213AA package

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 91 V levels
• Overvoltage protection in industrial equipment
• Clamping applications in high-temperature electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix D/TR against official Microchip documentation to confirm tape-and-reel packaging configuration. Ensure the ±1% tolerance variant matches design requirements, as other tolerances may exist within the CDLL5270 family. Cross-reference the DO-213AA footprint with PCB layout guidelines to guarantee mechanical compatibility during assembly.

Single Zener Diodes Selection Notes

Select this component when a high-voltage Zener reference is needed in a small surface-mount form factor. The 175°C rating makes it suitable for harsh environments where standard silicon diodes might fail. Consider the 400 Ohm impedance for noise-sensitive applications, as higher impedance may affect regulation stability under dynamic load conditions.

Single Zener Diodes Part Context

The CDLL5270D/TR belongs to Microchip's CDLL series of glass-passivated Zener diodes. This series is engineered for reliability in demanding electronic applications. The DO-213AA package offers a balance between thermal performance and space efficiency, making it a common choice for dense circuit board designs requiring discrete voltage regulation components.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 91 V Zener voltage, ±1% tolerance, and DO-213AA package. Verify that alternative manufacturers offer equivalent thermal ratings and impedance characteristics to ensure functional parity in existing designs.
