DZ23C3V0HE3-TP

Overview

The DZ23C3V0HE3-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 independent Zener diodes sharing a single ground pin. The nominal Zener voltage is 3.0 V, with a tolerance of ±5% (ranging from 2.85 V to 3.15 V). The device has a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a test current of 5.0 mA, a maximum Zener impedance of 95 Ω at the test current, and a maximum reverse leakage current of 50 µA at 1.0 V.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Common cathode configuration simplifies circuit layout by providing a shared ground reference.
• Tight voltage matching between the two internal diodes ensures consistent performance.
• Qualified for automotive applications under AEC-Q101 standards.

Applications

• Voltage reference circuits requiring dual stable voltage rails.
• Transient voltage suppression in low-voltage signal lines.
• Clamping applications for protecting sensitive electronic components.
• Automotive electronics systems meeting AEC-Q101 reliability requirements.

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement channels to avoid counterfeit parts. Confirm that the ordering suffix '-TP' corresponds to the Tape & Reel packaging format containing 3000 pieces per reel. Ensure compliance with RoHS directives and UL 94 V-0 flammability ratings as specified in the datasheet.

Selection Notes

Select this component when a dual-channel voltage regulation solution is needed in a minimal footprint. The common cathode topology is suitable for applications where both diodes share a common ground potential. Consider the 300 mW power rating and thermal resistance of 417°C/W for adequate heat dissipation in the intended environment.

Part Context

This part belongs to the DZ23C series of dual Zener diodes offered by 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 Halogen-free and Green product status, while the 'TP' suffix specifies the tape and reel packaging option.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, 300 mW power rating, and 3.0 V nominal voltage. Verify that alternative parts also offer a common cathode configuration and meet AEC-Q101 qualification if used in automotive contexts. Check for equivalent Zener impedance and leakage current specifications to ensure circuit compatibility.
