DZ23C30-G3-18

Overview

The DZ23C30-G3-18 is a dual silicon planar Zener diode in the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two independent diodes sharing a single ground terminal. The nominal Zener voltage is 30 V with a standard tolerance of ±5 %. Electrical testing is conducted at a test current (IZT) of 2 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual silicon planar Zener diodes integrated into a single compact surface-mount package
• Common cathode circuit configuration for simplified PCB routing
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Voltage reference circuits requiring dual stable potentials
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in low-power electronic assemblies

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm reel specifications and tape dimensions. Confirm RoHS compliance status and material categorization details directly from the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array is required in a minimal footprint. Ensure the operating current remains near the specified 2 mA test point to maintain accurate voltage regulation. Verify that the thermal resistance characteristics align with the target application's heat dissipation requirements.

Part Context

This part belongs to the Vishay DZ23-G series, which provides a wide range of Zener voltages from 2.2 V to 75 V. All devices in this series share identical physical packaging and electrical testing methodologies, differing primarily in their graded breakdown voltage values according to the E24 standard.

Replacement Considerations

Cross-reference other manufacturers offering dual Zener arrays in SOT-23 packages. Verify that substitute parts match the 30 V nominal voltage, ±5 % tolerance, and common cathode configuration to ensure functional compatibility.
