DZ23C5V1HE3-TP

Overview

The DZ23C5V1HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC) in an SOT-23 surface-mount package. It features a common cathode configuration with two integrated silicon junctions. The nominal Zener voltage is 5.1 V, with a tolerance range of 4.85 V to 5.36 V at a test current of 5.0 mA. Maximum Zener impedance is 60 Ohms at the test current and 480 Ohms at a knee current of 1.00 mA. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. It is AEC-Q101 qualified and RoHS compliant.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Common cathode configuration simplifies circuit layout and component placement.
• AEC-Q101 qualification ensures reliability for automotive electronic applications.
• Tight voltage matching between the two internal diodes maintains system balance.

Applications

• Automotive instrument cluster protection circuits
• Digital dashboard signal conditioning
• General-purpose voltage reference and clamping

Procurement Notes

Verify authenticity through authorized MCC distributors or direct channels to avoid counterfeit components. Confirm the specific suffix matches the required electrical characteristics and packaging format. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines before soldering. Cross-reference the ordering information with the official datasheet to validate the part number against the desired voltage rating.

Selection Notes

Select this component when a dual voltage reference or balanced clamping solution is required in a small footprint. The common cathode arrangement allows independent control of two voltage thresholds using a single ground connection. Consider the 300 mW power dissipation limit and thermal resistance when designing for high ambient temperatures. Verify that the 5.1 V nominal voltage aligns with the target circuit 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 2.4 V to 47 V, all housed in the same SOT-23 package. The HE3 designation indicates a halogen-free, green product formulation. The TP suffix specifies tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct replacements include other DZ23C5V1 variants from MCC, such as DZ23C5V1-TP. Cross-manufacturer equivalents must match the SOT-23-3 package, 5.1 V Zener voltage, 300 mW power rating, and dual common cathode configuration. Verify pinout compatibility and thermal characteristics before substitution.
