CDLL5272C

Single Zener Diodes Overview

The CDLL5272C is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA package. It features a nominal Zener voltage of 110 V with a tight tolerance of ±2%. The device operates within an extended temperature range from -65°C to +175°C and exhibits a maximum reverse leakage current of 100 nA at 84 V. Key electrical characteristics include a Zener impedance of 750 ohms and a forward current rating of 200 mA.

Single Zener Diodes Feature Summary

• High-precision voltage regulation with ±2% tolerance
• Extended high-temperature operation up to 175°C
• Compact surface-mount MELF form factor

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the ±2% tolerance variant distinct from standard versions. Confirm RoHS compliance status as some Microchip variants may not meet current directives. Ensure the DO-213AA package matches your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required under high-temperature conditions. The ±2% tolerance offers superior accuracy compared to standard 5% or 10% variants. Consider the low leakage current for high-impedance circuit designs where minimal current drain is critical.

Single Zener Diodes Part Context

This part belongs to the CDLL5272 series of Zener diodes from Microchip Technology. While sharing similar electrical profiles with the CDLL5272B, the 'C' suffix specifically denotes the tighter ±2% voltage tolerance. It utilizes the same DO-213AA surface-mount package for consistent mechanical integration.

Single Zener Diodes Replacement Considerations

The CDLL5272B serves as a functional substitute but provides only ±5% tolerance. Verify if the reduced precision meets your design margins. Other generic 110V Zener diodes in DO-213AA packages may require re-evaluation of thermal and leakage specifications.
