DZ23C2V4-G3-08

Overview

The Vishay DZ23C2V4-G3-08 is a silicon planar Zener diode in the DZ23-G series, housed in an SOT-23 package. It provides a nominal Zener voltage of 2.4 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 50 μA at 1 V. Dynamic resistance is specified at 100 Ω (max) at the test current. Power dissipation reaches 500 mW on lead-mounted configurations and 300 mW on FR-4 boards. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable small-signal regulation
• ESD protection exceeding 8 kV via human body model and 800 V via machine model
• Standardized grading according to international E24 voltage tolerances

Applications

• Voltage reference circuits requiring stable low-voltage biasing
• Overvoltage protection stages in signal processing paths
• Clamping applications within consumer electronics assemblies

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required tape-and-reel packaging format. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders.

Selection Notes

Select this component when a precise 2.4 V reference is needed in a compact surface-mount footprint. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures. Verify that the 100 Ω dynamic resistance meets the noise and stability requirements of the target circuit design.

Part Context

This part belongs to the DZ23-G series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, all utilizing the same SOT-23 package. The G3 suffix indicates green commercial grade compliance without halogenated flame retardants.

Replacement Considerations

Direct substitutes include other Vishay DZ23C2V4 variants such as DZ23C2V4-G3-18 for different reel sizes. Cross-brand replacements require matching the 2.4 V nominal voltage, ±5 % tolerance, and SOT-23 package dimensions.
