DZ23C3V3-7

Overview

The DZ23C3V3-7 is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two independent silicon junctions within a single molded plastic case. The nominal Zener voltage is 3.3 V, with a specified tolerance range of 3.1 V to 3.5 V at a test current of 5.0 mA. The device supports a maximum power dissipation of 300 mW and operates across a temperature range of -65°C to +150°C. Key electrical parameters include a maximum Zener impedance of 95 Ω at the test current and a typical temperature coefficient of -0.055 %/°C.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Common cathode configuration allows for simplified circuit routing and automated insertion.
• Manufactured using lead-free, halogen-free, and antimony-free materials compliant with RoHS directives.
• High reliability qualification meeting JEDEC standards for robust performance.

Applications

• Voltage reference circuits requiring stable low-voltage regulation.
• Transient voltage suppression (TVS) for protecting sensitive input lines.
• Clamping applications in signal conditioning and data acquisition systems.

Procurement Notes

Verify the specific ordering suffix when sourcing components. The datasheet indicates that commercial grade parts utilize the -7-F suffix, while automotive-grade variants require a Q-suffix. Confirm packaging details directly with the manufacturer or authorized distributors, as shipping quantities and reel specifications are subject to change. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component for applications requiring matched dual Zener characteristics in a minimal footprint. The tight voltage matching between the two diodes within the same case ensures consistent performance. Evaluate the thermal resistance and derating requirements if operating near the maximum power dissipation limit. Consider the negative temperature coefficient for low-voltage operation when designing precision analog circuits.

Part Context

This part belongs to the DZ23C series, which covers a wide range of Zener voltages from 2.7 V to 51 V. All devices in this family share the same physical SOT-23 package and mechanical dimensions, allowing for design flexibility without altering the board layout. The series provides options for both common cathode and common anode configurations to suit various circuit topologies.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, 300 mW power rating, and 3.3 V nominal voltage. Verify that substitute components offer comparable Zener impedance and temperature coefficients. Automotive applications may require equivalents qualified to AEC-Q101 standards.
