CDLL5242C

Single Zener Diodes Overview

The CDLL5242C 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 12 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 Zener impedance of 30 Ohms. With a maximum reverse leakage current of 1 uA, it provides stable voltage regulation suitable for precision electronic circuits requiring compact form factors.

Single Zener Diodes Feature Summary

• High-precision voltage regulation with ±2% tolerance
• Extended operating temperature range up to 175°C
• Compact surface-mount DO-213AA package design

Single Zener Diodes Applications

• Precision voltage reference circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., /TR) for packaging configuration when ordering. Confirm that the DO-213AA footprint matches the target PCB layout. Ensure the ±2% tolerance requirement aligns with circuit specifications. Check for RoHS compliance status if required by project standards. Validate manufacturer authenticity through authorized distribution channels.

Single Zener Diodes Selection Notes

Select this component when high accuracy is critical due to the ±2% voltage tolerance. The wide temperature range supports operation in harsh environments. The small DO-213AA package is ideal for space-constrained designs. Consider the low leakage current for high-impedance applications. Compare against standard 5% tolerance variants if cost is a primary driver.

Single Zener Diodes Part Context

This part belongs to Microchip's CDLL series of glass-passivated Zener diodes. These components are engineered for reliability in demanding industrial and commercial applications. The series offers various voltage options within the same physical footprint, simplifying supply chain management for multi-voltage designs.

Single Zener Diodes Replacement Considerations

The CDLL5242C/TR is a reel-packaged variant of the same electrical specification. Verify pinout compatibility before substituting with other manufacturers' DO-213AA devices. Ensure equivalent voltage and impedance ratings are maintained.
