CZRW4689-G

Single Zener Diodes Overview

The Comchip Technology CZRW4689-G is a surface-mount Zener diode housed in an SOD-123 package. It provides a nominal Zener voltage of 5.1 V with a tolerance range of 4.85 V to 5.36 V at a test current of 50 µA. The device supports a maximum power dissipation of 350 mW and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum reverse leakage current of 10 µA and a Zener impedance of 3 Ω.

Single Zener Diodes Procurement Notes

Verify component authenticity by checking the marking code 'CU' and cathode band orientation against the datasheet specifications. Confirm the SOD-123 package dimensions and terminal solderability standards prior to integration into printed circuit board assemblies.

Single Zener Diodes Selection Notes

Select this component when a precise 5.1 V reference is required in space-constrained designs. Ensure the operating environment remains within the specified thermal limits and that the low test current requirement aligns with the target circuit design constraints.

Single Zener Diodes Part Context

This part belongs to the CZRW4678-G through CZRW4717-G series from Comchip Technology. The series covers a wide Zener voltage range from 1.8 V to 43 V, all sharing identical mechanical packaging and general electrical rating profiles for standardized supply chain management.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other SOD-123 Zener diodes with a 5.1 V nominal voltage, 350 mW power rating, and matching tolerance specifications. Verify pinout polarity and thermal resistance parameters before implementation.
