DZ23C17HE3-TP

Overview

The DZ23C17HE3-TP is a dual Zener diode in a common cathode configuration, manufactured by Micro Commercial Components (MCC). It operates within a voltage range of 2.4 to 47 Volts and features a maximum power dissipation of 300 mW. The device utilizes an SOT-23 package with three terminals. Electrical specifications for the DZ23C17 variant include a nominal Zener voltage of 17 V, tested at a current of 5.0 mA, with a maximum impedance of 40 Ω. The component meets AEC-Q101 qualification standards and supports an operating junction temperature range from -55°C to +150°C.

Feature Summary

• Dual Zener diodes integrated into a single common cathode package
• AEC-Q101 qualified for automotive reliability requirements
• Tight voltage matching between internal diodes with delta V-Z less than or equal to 5 percent
• Halogen-free green device construction with UL 94 V-0 flammability rating

Applications

• Automotive electronic circuits requiring dual voltage references
• Clamping applications for signal protection lines
• Voltage regulation tasks in compact surface-mount designs

Procurement Notes

Verify authenticity through authorized MCC distributors to avoid counterfeit components. Confirm RoHS compliance status via official documentation before integration. Check for end-of-life notifications as discontinuance may affect long-term supply stability. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines during handling.

Selection Notes

Select this component when dual independent Zener functions are required in a minimal footprint. Verify that the 17 V nominal breakdown aligns with circuit reference needs. Consider the 300 mW power limit and thermal resistance of 417°C/W for heat management. Ensure the SOT-23 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the DZ23C series of dual Zener diodes offered by Micro Commercial Components. The series covers voltages from 2.4 V to 47 V in the SOT-23 package. The HE3 suffix indicates Halogen-free Epoxy, while TP denotes Tape and Reel packaging with a quantity of 3000 pieces per reel.

Replacement Considerations

Direct substitutes must match the dual common cathode structure, SOT-23 package, and 17 V nominal voltage. Verify equivalent electrical parameters including impedance and power dissipation. Cross-reference specific manufacturer datasheets for pinout compatibility and thermal characteristics.
