DZ23C10HE3-TP

Overview

The DZ23C10HE3-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 dissipates up to 300 mW. The device features an operating junction temperature range from -55°C to +150°C and a thermal resistance of 417°C/W. For the DZ23C10HE3 variant specifically, the nominal Zener voltage is 10 V with a test current of 5.0 mA. Maximum Zener impedance is 15 Ω at this test current, while leakage current remains below 0.1 µA at 7.5 V reverse voltage. The component is AEC-Q101 qualified, RoHS compliant, and housed in an SOT-23 package.

Feature Summary

• Dual Zener diodes integrated in a single common cathode package for space-efficient designs.
• Tight voltage matching between both diodes ensures consistent performance within one case.
• Qualified for automotive applications under the AEC-Q101 standard.
• Halogen-free construction with UL 94 V-0 flammability rated epoxy.

Applications

• Automotive electronic circuits requiring dual voltage references.
• Signal clamping and protection in compact surface-mount layouts.
• Voltage regulation tasks in low-power consumer electronics.

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS directives and halogen-free requirements if mandated by project specifications. Check for any recent datasheet revisions that may affect mechanical dimensions or electrical tolerances before finalizing procurement orders.

Selection Notes

Select the DZ23C10HE3-TP when two matched Zener diodes are needed in a shared ground reference. The common cathode structure simplifies PCB routing compared to discrete components. Consider the 300 mW power dissipation limit and the 417°C/W thermal resistance for adequate heat management. Verify that the 10 V nominal voltage aligns with the target circuit requirements and that the SOT-23 footprint fits the design constraints.

Part Context

This component belongs to the DZ23C series of dual Zener diodes produced by Micro Commercial Components. The series covers a wide voltage spectrum from 2.4 V to 47 V, all sharing the same SOT-23 physical package and internal architecture. The HE3 designation indicates a lead-free, halogen-free green product compliant with environmental standards. The TP suffix specifies tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct substitutes must match the dual common cathode configuration, SOT-23 package, and 10 V nominal voltage. Verify that alternative parts meet the same AEC-Q101 qualification and 300 mW power rating. Electrical parameters such as Zener impedance and leakage current should be comparable to ensure circuit functionality without modification.
