DDZ9712Q-7

Single Zener Diodes Overview

The DDZ9712Q-7 is a surface mount low current Zener diode manufactured by Diodes Incorporated. It features a nominal Zener voltage of 28 V with a range of 26.60 V to 29.40 V, specified at a test current of 50 µA. The device has a maximum reverse leakage current of 0.05 µA at 21.2 V and operates within a temperature range of -65°C to +150°C. It dissipates 500 mW on an FR-4 PCB at +75°C lead temperature and is housed in an SOD-123 package.

Single Zener Diodes Procurement Notes

Verify the component matches the exact part number DDZ9712Q-7 to ensure correct voltage specifications. Confirm that the supplier provides documentation proving AEC-Q101 qualification if automotive use is intended. Check for compliance with RoHS and halogen-free requirements as stated in the datasheet. Ensure the packaging type corresponds to the ordered suffix.

Single Zener Diodes Selection Notes

Select this component when a precise 28V reference is needed in space-constrained designs using the SOD-123 footprint. Consider its low leakage current and tight tolerance for sensitive analog circuits. Verify thermal management capabilities based on the specified power dissipation limits on FR-4 substrates.

Single Zener Diodes Part Context

This part belongs to the DDZ9678-DDZ9717 series of surface mount low current Zener diodes. The 'Q' suffix indicates it is an automotive-grade variant qualified to AEC-Q101 standards. These devices are designed for automated assembly processes and offer sharp breakdown characteristics with very low leakage currents compared to standard Zener diodes.

Single Zener Diodes Replacement Considerations

Substitutes must match the 28V nominal Zener voltage, SOD-123 package, and 500mW power rating. Automotive replacements require AEC-Q101 qualification. Verify leakage current and tolerance specifications align with the original design requirements.
