DZ23C13HE3-TP

Overview

The DZ23C13HE3-TP is a dual Zener diode in a common cathode configuration, manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 13V with a tolerance range of 12.35V to 13.65V at a test current of 5.0mA. The device has a maximum power dissipation of 300mW and operates within a junction temperature range of -55°C to +150°C. Packaged in an SOT-23 surface-mount case, it exhibits a maximum Zener impedance of 25Ω at the test current and 170Ω at a leakage current of 0.1mA. The component is AEC-Q101 qualified and RoHS compliant.

Feature Summary

• Dual Zener diodes integrated in a single common cathode package for space-saving designs.
• Tight voltage matching between the two internal diodes with a delta V_Z of less than or equal to 5%.
• Automotive-grade qualification ensuring reliability under specified thermal conditions.
• Halogen-free construction meeting environmental standards.

Applications

• Voltage reference circuits requiring matched dual outputs.
• Over-voltage protection stages in automotive electronics.
• Clamping applications in signal conditioning paths.

Procurement Notes

Verify authenticity through authorized MCC distributors to avoid counterfeit components. Confirm the specific suffix matches the required packaging format. Ensure the ordering part number aligns with the intended voltage tolerance and package type. Request traceability documentation for quality assurance purposes. Validate compliance with project-specific material restrictions before final procurement.

Selection Notes

Select this component when a matched pair of Zener diodes is required in a minimal footprint. The common cathode arrangement simplifies circuit layout compared to discrete components. Consider the 300mW power rating and thermal resistance limits for the operating environment. Verify that the 13V nominal voltage fits the target application requirements.

Part Context

This part belongs to the DZ23C series of dual Zener diodes from Micro Commercial Components. The series covers a wide voltage range from 2.4V to 47V in the same SOT-23 package. The HE3 designation indicates a high-efficiency epoxy formulation, while the TP suffix specifies tape and reel packaging.

Replacement Considerations

Direct substitutes include other DZ23C13 variants from different manufacturers offering identical pinouts and electrical characteristics. Cross-reference with Diodes Incorporated DZ23C13 for functional equivalence. Verify package dimensions and marking codes match the existing board design.
