CZRUR52C18

Single Zener Diodes Overview

The Comchip Technology CZRUR52C18 is a single Zener diode designed for surface-mount applications. It features an 18 V nominal Zener voltage with a 5% tolerance and operates within a power dissipation limit of 150 mW. The device utilizes an SOD-523F-2 package, measuring 1.8 mm in length, 1 mm in width, and 0.85 mm in height. Electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 50 Ohms at a test current of 5 mA, and a forward voltage of 900 mV. It supports an operating temperature range from -55 C to +125 C.

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure correct voltage rating and package type. Confirm RoHS compliance status and datasheet revisions prior to integration. Cross-reference electrical parameters such as impedance and leakage current with design requirements. Ensure sourcing channels provide authentic components to avoid counterfeit risks.

Single Zener Diodes Selection Notes

Select this component when a fixed 18 V reference is required in a small form factor. Consider the 150 mW power dissipation limit for thermal management in enclosed designs. Evaluate the 50 Ohm impedance value for high-frequency response needs. Compare the SOD-523F-2 dimensions against available PCB land patterns to ensure mechanical compatibility.

Single Zener Diodes Part Context

This component belongs to the Comchip Technology Zener diode series, specifically engineered for surface-mount technology. It shares the SOD-523F-2 package profile with other variants in the lineup, differing primarily in breakdown voltage specifications. The series targets general-purpose regulation tasks where low profile and reliable performance are prioritized.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 18 V Zener voltage, 150 mW power rating, and SOD-523F-2 package. Verify equivalent electrical parameters including impedance and leakage current. Ensure the replacement component meets the same temperature range and regulatory standards.
