CDLL5275D

Single Zener Diodes Overview

The CDLL5275D 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 140 V with a tolerance of ±20%. The device operates within a temperature range of -65°C to +175°C and has a maximum reverse leakage current of 100 nA at 101 V. The Zener impedance is specified at 1.3 kΩ, and it supports a forward current of 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 140 V for circuit protection and reference applications
• Capable of operating in extreme environments from -65°C to +175°C
• Utilizes a compact surface mount DO-213AA-2 package for automated assembly

Single Zener Diodes Applications

• Voltage regulation in high-voltage circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in industrial control systems

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., /TR) if reel packaging is required, as standard listings may vary. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as some variants in this series may not be compliant. Ensure the DO-213AA-2 footprint matches your PCB design constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 140 V regulation point is needed in a small form factor. The wide operating temperature range makes it suitable for harsh industrial or automotive environments. Consider the ±20% tolerance if tight voltage precision is not critical for the application.

Single Zener Diodes Part Context

This part belongs to the CDLL52xx series of single Zener diodes from Microchip Technology. These devices are engineered for reliability in demanding conditions, offering robust performance in voltage clamping and regulation tasks where space is limited.

Single Zener Diodes Replacement Considerations

Check for compatible parts such as CDLL5275D/TR if tape-and-reel packaging is specifically required. Verify pinout compatibility with the DO-213AA-2 package when substituting with other manufacturers' equivalents.
