CDLL5261D/TR

Single Zener Diodes Overview

The CDLL5261D/TR is a single Zener diode manufactured by Microchip Technology, designed for surface mount applications in the DO-213AA-2 package. It features a nominal Zener voltage of 47 V with a tight tolerance of ±1%. The device operates within a temperature range of -65°C to +175°C and has a maximum reverse leakage current of 100 nA. Key electrical parameters include a Zener impedance of 150 Ohms at a test current of 2.2 mA, a forward current rating of 200 mA, and a forward voltage of 1.1 V.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±1% tolerance
• Extended high-temperature operational capability up to 175°C
• Compact surface-mount design in DO-213AA-2 package

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection systems
• Temperature-compensated regulator designs

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates the ±1% tolerance variant when sourcing. Confirm the DO-213AA-2 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -65°C to +175°C range to maintain performance integrity. Check for RoHS compliance status as indicated in official documentation.

Single Zener Diodes Selection Notes

Select this component when precise voltage clamping is required under varying thermal conditions. The low leakage current makes it suitable for high-impedance circuits. Consider the 200 mA forward current rating if the device may experience transient forward biasing. The tight tolerance reduces the need for external calibration in critical applications.

Single Zener Diodes Part Context

This part belongs to the CDLL5261 series of Zener diodes from Microchip Technology. The series offers various voltage options within the same compact package family. The 'TR' suffix typically denotes tape and reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 47V Zener voltage, ±1% tolerance, and DO-213AA-2 package. Verify equivalent thermal characteristics and leakage specifications before substitution.
