Overview
The DZ23C47HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It provides a nominal Zener voltage of 4.7V with a maximum impedance of 78Ω at a test current of 5.0mA. The device supports a power dissipation of 300mW and operates within a junction temperature range of -55°C to +150°C. It features a thermal resistance of 417°C/W from junction to ambient. The component is AEC-Q101 qualified, RoHS compliant, and halogen-free.
Feature Summary
- Dual Zener diodes integrated in a single common cathode case for space-saving designs.
- Tight voltage matching between the two internal diodes ensures consistent performance.
- Automotive-grade qualification suitable for demanding electronic environments.
- RoHS compliant and halogen-free construction for environmental safety.
Applications
- Voltage reference circuits requiring matched dual outputs.
- Over-voltage protection for sensitive automotive electronics.
- Clamping applications in industrial control systems.
Procurement Notes
Verify authenticity by purchasing only from Micro Commercial Components or their authorized distributors. Counterfeit components pose significant risks; unauthorized sources do not provide warranty coverage. Ensure the ordering suffix matches the required packaging format, such as tape and reel quantities specified in the official documentation.
Selection Notes
Select this component when a compact dual Zener solution is required in an SOT-23 footprint. The 4.7V nominal voltage and 300mW power rating define its operational limits. Consider the 78Ω impedance value for dynamic regulation requirements. Verify that the operating temperature range meets the specific application environment constraints.
Part Context
This part belongs to the DZ23C series of dual Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4V to 47V. All devices share the same SOT-23 package and electrical characteristics structure, differing primarily in their specific Zener voltage ratings and corresponding marking codes.
Replacement Considerations
Direct replacements must match the SOT-23-3 package, 300mW power rating, and 4.7V nominal voltage. Verify that substitute parts also meet AEC-Q101 qualification if automotive use is intended. Check for identical pinout configurations and thermal resistance values to ensure compatibility.
FAQ
What is the maximum reverse current for the DZ23C47HE3-TP?
The maximum reverse current (IR) is 5.0µA when measured at a reverse voltage (VR) of 2.0V.
How are the two Zener diodes configured internally?
The device contains two Zener diodes connected in a common cathode configuration within a single SOT-23 package.
What is the tolerance on the Zener voltage difference between the two diodes?
The difference in Zener voltage (△ VZ) between the two diodes in one case is specified to be less than or equal to 5%.
