DZ23C11-HE3-08

Overview

The DZ23C11-HE3-08 is a dual common cathode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features two independent Zener elements housed in a compact SOT-23-3 surface-mount package. The device provides a nominal Zener voltage of 11 V with a tolerance of ±5%. Each element supports a maximum power dissipation of 300 mW, resulting in a total array power rating of 600 mW. The component operates within a temperature range of -55°C to +150°C and is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual common cathode configuration integrates two Zener elements into a single compact footprint.
• AEC-Q101 qualification ensures reliability for demanding automotive electronic environments.
• High thermal stability allows operation across an extended industrial temperature range.

Applications

• Automotive circuit protection and voltage reference applications
• Clamping circuits in automotive infotainment systems
• Voltage regulation in automotive sensor interfaces

Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as variations exist between tape-and-reel quantities. Confirm RoHS compliance status through the official datasheet before integration. Check current production status as manufacturing changes may occur. Ensure the selected variant matches the required voltage tolerance and package type for the design.

Selection Notes

Select this component when a dual Zener solution is required in a minimal SOT-23-3 footprint. The common cathode arrangement simplifies biasing compared to separate discrete components. Verify that the 11 V breakdown voltage aligns with the target clamping or reference requirements. Consider the 300 mW per element limit for thermal management in dense PCB layouts.

Part Context

This part belongs to the DZ23 series of dual Zener arrays from Vishay. The HE3 suffix indicates a Halogen-free and RoHS-compliant version with improved environmental characteristics. Similar parts in the series offer different voltage ratings while maintaining the same package and electrical interface constraints.

Replacement Considerations

Direct replacements include other Vishay DZ23 series variants with compatible voltages. Cross-manufacturer equivalents must match the SOT-23-3 package, 11 V nominal voltage, and dual common cathode configuration. Verify pinout compatibility and thermal performance before substitution.
