CDLL5224B/TR

Single Zener Diodes Overview

The CDLL5224B/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It utilizes the DO-213AA-2 (MELF) leadless package with double plug construction and metallurgic bonding. The device provides a nominal Zener voltage of 2.8 V with a tight tolerance of ±5%. It operates within an extended temperature range from -65°C to +175°C and features a maximum power dissipation of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 75 µA at 1 V and a Zener impedance of 30 Ohms.

Single Zener Diodes Feature Summary

• Double plug construction with metallurgic bonding for enhanced reliability in surface-mount environments
• Extended operating temperature range supporting high-temperature industrial applications up to 175°C
• Tight voltage tolerance ensuring precise regulation performance in sensitive circuits

Single Zener Diodes Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Overvoltage protection in compact surface-mount designs
• Clamping applications in high-reliability electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration when sourcing. Confirm compliance requirements as the component may not meet RoHS standards depending on the manufacturing batch. Ensure the DO-213AA-2 footprint matches the design layout. Check for any recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 2.8 V Zener voltage with ±5% tolerance is required in a MELF package. Consider the 500 mW power rating and thermal derating characteristics above 125°C. Evaluate the low leakage current specifications for precision applications. Compare against through-hole alternatives if board space permits, noting the surface-mount orientation benefits.

Single Zener Diodes Part Context

This part belongs to the CDLL5221 thru CDLL5272B series of Zener diodes produced by Microchip Technology. The series offers various voltage options in the same DO-213AA-2 package form factor. These devices are engineered for high-reliability applications where small size and robust construction are critical. The series supports both standard and military-grade variants.

Single Zener Diodes Replacement Considerations

Direct replacements include other CDLL5224B variants from Microchip such as the non-tape version CDLL5224B. Cross-brand equivalents in the DO-213AA-2 package with matching 2.8 V and ±5% specifications should be verified for pin compatibility and thermal performance.
