DZ23C7V5-7-F

Overview

The DZ23C7V5-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 7.5 V with a range of 7.0 to 7.9 V at a test current of 5.0 mA. Maximum power dissipation is 300 mW, and the maximum Zener impedance (ZZT) is 7.0 Ω at 1 kHz. The typical temperature coefficient is +0.050 %/°C, and the minimum reverse voltage is 5.0 V at 0.1 µA leakage current. Operating and storage temperatures range from -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common cathode configuration for space-saving designs.
• High reliability qualification meeting JEDEC standards for robust performance.
• Environmentally compliant construction that is fully lead-free, halogen-free, and antimony-free.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Over-voltage protection stages in signal conditioning paths.
• Clamping applications in high-reliability electronic assemblies.

Procurement Notes

Verify the complete part number against official manufacturer documentation before procurement. Confirm that the specific suffix matches the required commercial grade and packaging format. Ensure compliance with RoHS and REACH directives relevant to the target market. Cross-reference the datasheet revision date to validate electrical characteristics against current production batches.

Selection Notes

Select this component when a dual Zener array is required in a compact SOT-23 footprint. Evaluate the thermal resistance of 417 °C/W and derating curves if operating near maximum power limits. Consider the positive temperature coefficient for stability requirements in varying ambient conditions. Verify that the 7.0 Ω impedance meets the dynamic regulation needs of the circuit design.

Part Context

This device belongs to the DZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V. The DZ23C7V5-7-F specifically addresses the 7.5 V nominal requirement within this family, sharing identical mechanical dimensions and thermal characteristics with other variants in the lineup.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's automotive grade Q-suffix variants or the AZ23 series for common anode configurations if polarity requirements differ. Direct pin-compatible replacements should be verified against the latest datasheet specifications.
