DZ23C2V7HE3-TP

Overview

The DZ23C2V7HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC) in an SOT-23 package. It features a common cathode configuration with two independent Zener diodes housed in a single case. The nominal Zener voltage is 2.7 V, with a tolerance of ±5% between the two devices within the same package. Maximum power dissipation is 300 mW at 25°C, and the maximum Zener impedance is 83 Ω at a test current of 5.0 mA. The device operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• AEC-Q101 qualified for use in automotive electronic systems.
• Tight voltage matching ensures consistent performance between the two internal diodes.
• Halogen-free construction compliant with green manufacturing standards.

Applications

• Automotive circuit protection and voltage reference applications.
• Signal conditioning and clamping in digital logic interfaces.
• Over-voltage protection for sensitive input lines.

Procurement Notes

Verify component authenticity through authorized MCC distributors or direct procurement channels to mitigate counterfeit risks. Confirm RoHS compliance status and specific packaging quantities prior to ordering. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to maintain solderability and reliability during assembly processes.

Selection Notes

Select this component when a dual voltage reference or protection scheme is required in a minimal footprint. The common cathode configuration allows for shared ground connections. Verify that the 300 mW power rating and 2.7 V breakdown voltage align with the target circuit's operational limits and thermal management capabilities.

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 utilizing the SOT-23 surface-mount package. The HE3 suffix indicates Halogen-free and RoHS-compliant epoxy materials, while the TP suffix denotes tape and reel packaging for automated insertion.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, 2.7 V nominal voltage, and dual common cathode configuration. Verify that alternative components meet the same AEC-Q101 automotive qualification and 300 mW power dissipation ratings to ensure functional equivalence in existing designs.
