DZ23C12-7

Overview

The DZ23C12-7 is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common cathode configuration with two independent Zener elements within a single case. The nominal Zener voltage ranges from 11.4 V to 12.7 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 20 Ω at the test current and 90 Ω at a leakage current of 1.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual Zeners in Common Cathode Configuration
• Ideally Suited for Automated Insertion
• Totally Lead-Free & Fully RoHS Compliant

Applications

• Voltage regulation circuits
• Clamping applications
• Reference voltage generation

Procurement Notes

Verify the specific ordering suffix when sourcing components. The standard commercial version utilizes the -7 suffix, while automotive-grade variants require the Q-7-F suffix. Confirm that the procurement channel provides original manufacturer documentation to ensure compliance with JEDEC standards and high-reliability requirements.

Selection Notes

Select this component based on the required Zener voltage tolerance and impedance characteristics. Ensure the application circuit can accommodate the specified thermal resistance and power dissipation limits. Verify that the operating environment remains within the defined junction and storage temperature ranges for reliable performance.

Part Context

This part belongs to the DZ23C series of dual surface mount Zener diodes. The series covers a wide voltage range from 2.7 V to 51 V. All devices share the same SOT-23 footprint and common cathode topology, allowing for consistent board layout across different voltage reference designs.

Replacement Considerations

Direct replacements include other DZ23C12 variants from Diodes Incorporated. Cross-manufacturer equivalents must match the SOT-23 package, 300 mW power rating, and 12 V nominal voltage specifications.
