DZ23C24-7-F

Overview

The DZ23C24-7-F is a dual surface mount Zener diode from Diodes Incorporated, housed in an SOT23 package. It features a common cathode configuration with two independent Zener diodes sharing a single ground reference. The device has a maximum power dissipation of 300mW and operates within a temperature range of -65°C to +150°C. For the DZ23C24 variant, the Zener voltage ranges from 22.8V to 25.6V at a test current (IZT) of 5.0mA. The maximum Zener impedance (ZZT) is 80Ω at IZT, while the impedance at low current (ZZK, 1.0mA) is 220Ω. The typical temperature coefficient is +0.090%/°C, and the minimum reverse voltage at IR = 0.1µA is 18.0V.

Feature Summary

• Dual Zener diodes integrated in a single common cathode SOT23 package for space-efficient designs.
• High reliability qualification meeting JEDEC standards for demanding applications.
• Environmentally compliant construction that is lead-free, halogen-free, and antimony-free.

Applications

• Voltage regulation circuits requiring dual reference levels in compact form factors.
• Over-voltage protection stages in consumer electronics.
• Clamping applications in signal conditioning paths.

Procurement Notes

Verify the specific ordering suffix matches the required commercial or automotive grade. Confirm packaging details such as tape and reel quantities against current distributor listings. Ensure the component meets RoHS 3 and REACH regulatory requirements for the target market. Cross-reference the date code and marking information to confirm manufacturing origin and authenticity before integration into production lines.

Selection Notes

Select this component when a dual Zener solution is needed in an SOT23 footprint. Verify that the Zener voltage range of 22.8V to 25.6V aligns with circuit requirements. Check that the 300mW power dissipation limit is sufficient for the expected operating conditions. Consider the thermal resistance of 417°C/W for heat management calculations on the PCB layout.

Part Context

This part belongs to the DZ23C series, which offers various Zener voltage options from 2.7V to 51V in the same SOT23 package. The series provides consistent mechanical dimensions and electrical testing methodologies across different voltage ratings. The -7-F suffix indicates commercial grade qualification with standard tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct pin-compatible replacements may exist in other manufacturers' SOT23 dual Zener portfolios. Verify electrical parameters including Zener voltage tolerance, impedance, and power dissipation match or exceed original specifications. Ensure the replacement maintains the common cathode configuration and RoHS compliance status.
