CDLL5260D/TR

Single Zener Diodes Overview

The CDLL5260D/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a nominal Zener voltage of 43 V with a tight tolerance of ±1%. The device operates within an extended temperature range from -65 °C to +175 °C. It utilizes the DO-213AA (SOD-80) package and supports a maximum forward current of 200 mA with a forward voltage drop of 1.1 V at that current level.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±1% tolerance
• Extended high-temperature operational capability up to 175 °C
• Compact surface-mount SOD-80 packaging

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection in sensitive electronics
• Clamping applications in signal processing

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates reel packaging when ordering. Confirm the ±1% tolerance variant matches design requirements, as other tolerances may exist in the series. Ensure the DO-213AA footprint compatibility with PCB layout. Check latest datasheets for any updates on RoHS compliance status or pin configuration changes.

Single Zener Diodes Selection Notes

Select this component when precise voltage clamping is required under high thermal stress conditions. The ±1% tolerance makes it suitable for critical reference applications where standard 5% or 10% variants are insufficient. Consider the low leakage characteristics and fast response time inherent to the DO-213AA package for high-speed switching environments.

Single Zener Diodes Part Context

This part belongs to the CDLL5260 series of small-signal Zener diodes. It shares the same physical package and general electrical characteristics as other variants in the series, differing primarily in the specific Zener voltage rating. The series is widely used in consumer and industrial electronics requiring reliable voltage regulation in compact form factors.

Single Zener Diodes Replacement Considerations

Direct substitutes include other CDLL5260 series parts with identical voltage ratings but different tolerances if precision allows. Cross-reference with equivalent SOD-80 Zener diodes from other manufacturers ensuring matching 43V nominal voltage and ±1% tolerance specifications.
