DZ23C20-HE3-18

Overview

The DZ23C20-HE3-18 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. The device is housed in an SOT-23-3 surface-mount package, suitable for automated assembly. It operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 qualification for automotive applications. The component complies with RoHS3 standards and is classified as End-of-Life (EOL).

Feature Summary

• Dual common cathode configuration integrates two Zener diodes into a single compact SOT-23-3 package.
• AEC-Q101 qualified for reliability in automotive electronic environments.
• High thermal stability supports operation across extended industrial temperature ranges.

Applications

• Voltage reference circuits requiring dual independent references.
• Clamping and protection stages in automotive signal lines.
• Precision biasing networks in portable electronic devices.

Procurement Notes

This component has reached End-of-Life status and is no longer in active production. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should initiate replacement strategies immediately to ensure supply chain continuity for existing products.

Selection Notes

Select this part when a dual common cathode Zener array is required in an SOT-23-3 footprint. Ensure the 20 V nominal voltage aligns with circuit requirements. Verify that the 300 mW power rating suffices for the expected operating conditions. Confirm compatibility with AEC-Q101 standards if used in automotive systems.

Part Context

The DZ23C20-HE3-18 belongs to the DZ23 series of Zener diode arrays from Vishay. This series provides integrated solutions for space-constrained designs requiring multiple voltage references. The HE3 suffix indicates a lead-free and halogen-free compliant variant, adhering to modern environmental regulations for semiconductor components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers must evaluate alternative manufacturers offering similar dual Zener arrays in SOT-23-3 packages with comparable electrical characteristics.
