DZ23C6V2-7

Overview

The DZ23C6V2-7 is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 6.2 V with a range of 5.8 V to 6.6 V at a test current of 5.0 mA. Maximum Zener impedance is 10 Ω at IZT = 5.0 mA and 200 Ω at IZK = 1.0 mA. Power dissipation is rated at 300 mW, with a thermal resistance (junction to ambient) of 417 °C/W. Operating and storage temperature ranges span from -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common cathode configuration for space-efficient designs.
• High reliability qualification meeting JEDEC standards for robust performance.
• Lead-free construction fully compliant with RoHS directives and halogen/antimony free.

Applications

• Voltage reference circuits requiring dual stable potentials.
• Clamping and protection stages in signal processing paths.
• General purpose voltage regulation in compact electronic assemblies.

Procurement Notes

Verify the complete part number against official documentation, as suffixes such as -7-F denote specific commercial packaging configurations. Confirm that the required automotive grade variants are identified separately if AEC-Q101 qualification is necessary for the target application environment.

Selection Notes

Select this component when a dual Zener solution in a common cathode topology is required within a small SOT-23 footprint. Ensure the 300 mW power dissipation limit and 417 °C/W thermal resistance are compatible with the PCB layout and ambient operating conditions to prevent junction overheating.

Part Context

This device belongs to the DZ23C series, which encompasses a wide range of Zener voltages from 2.7 V to 51 V. All members share identical mechanical dimensions, pinout configurations, and thermal characteristics, allowing for design flexibility while maintaining consistent board space requirements across different voltage specifications.

Replacement Considerations

Direct replacements include other DZ23C6V2 variants from Diodes Incorporated or equivalent dual Zener arrays from other manufacturers offering matching SOT-23 packages and 6.2 V common cathode configurations.
