DZ23C20-HE3-08

Overview

The DZ23C20-HE3-08 is a dual common cathode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 20 V with a 5% tolerance and a maximum power dissipation of 300 mW per diode. The device utilizes an SOT-23-3 surface-mount package and operates within a junction temperature range of -55°C to +150°C. It holds AEC-Q101 qualification for automotive applications and complies with RoHS3 standards.

Feature Summary

• Dual common cathode configuration in a compact SOT-23-3 package
• AEC-Q101 qualified for automotive reliability requirements
• High thermal stability with a maximum junction temperature of 150°C

Applications

• Automotive voltage reference circuits
• Transient voltage suppression in low-voltage lines
• Clamping applications in automotive electronics

Procurement Notes

Verify the specific HE3 suffix against current manufacturer documentation, as product status may have changed. Confirm availability through authorized distributors or direct manufacturer channels. Ensure compliance with RoHS3 directives and AEC-Q101 automotive grade requirements for the intended application environment.

Selection Notes

Select this component when a dual common cathode Zener array is required in an SOT-23-3 footprint. The 20 V nominal voltage and 300 mW power rating suit low-power clamping tasks. Verify that the 5% tolerance meets circuit precision needs and that the SOT-23-3 thermal characteristics are sufficient for the operating conditions.

Part Context

This part belongs to the DZ23 series of dual Zener arrays from Vishay. These devices are designed for space-constrained surface-mount applications requiring dual voltage references or protection functions. The HE3 suffix indicates Halogen-free and RoHS compliant packaging.
