CDLL5523BE3

Single Zener Diodes Overview

The CDLL5523BE3 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a tolerance of 5%. The device operates in the DO-213AA-2 (SOD-80) surface-mount package and supports a maximum power dissipation of 500 mW. Electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a Zener impedance of 17 Ohms measured at a test current of 20 mA. The component is rated for an operating temperature range from -65°C to +175°C and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a 5.1 V nominal breakdown voltage.
• Capable of handling up to 500 mW power dissipation in a compact SMD form factor.
• Engineered for high-temperature reliability with operation up to 175°C.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Over-voltage protection stages in sensitive electronic systems.
• Clamping applications for transient voltage suppression.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' confirms lead-free compliance and RoHS status as per Microchip documentation. Confirm the package type matches the required DO-213AA-2 footprint for PCB layout compatibility. Ensure the 5% voltage tolerance aligns with circuit design requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V regulation point is required in a surface-mount assembly. The DO-213AA-2 package offers space efficiency compared to through-hole alternatives. Consider the 500 mW power rating to ensure adequate thermal headroom under continuous operating conditions within the specified temperature range.

Single Zener Diodes Part Context

This part belongs to the CDLL55xx series of small-signal Zener diodes produced by Microchip Technology. The series utilizes the DO-213AA-2 package, providing a standardized solution for low-power voltage regulation tasks in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 5.1 V Zener diodes in the DO-213AA-2 package. Verify that substitute parts meet or exceed the 500 mW power dissipation and 175°C maximum junction temperature specifications.
