DZ23C15-G3-18

Overview

The DZ23C15-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 15 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and has a maximum dynamic resistance of 30 Ω. Electrical characteristics include a reverse leakage current of 50 nA at 12 V and a temperature coefficient ranging from 7 to 9 x 10⁻⁴/°C. It supports an operating temperature range of -55 °C to +150 °C and provides ESD protection exceeding 8 kV (HBM) and 800 V (MM).

Feature Summary

• Green commercial grade construction compliant with material categorization standards.
• ESD capability exceeding 8 kV via human body model and 800 V via machine model.
• Standardized grading according to international E24 voltage tolerance specifications.

Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection for sensitive electronic components.
• Clamping applications in signal processing paths.

Procurement Notes

Verify that the ordering code matches the specific suffix required for the desired tape and reel quantity. Confirm RoHS compliance status through official documentation before finalizing purchase orders. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain component integrity during assembly.

Selection Notes

Select this component when a 15 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the thermal resistance values if power dissipation exceeds standard limits. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in a standardized SOT-23 package. The G3 suffix indicates green, commercial grade construction without halogenated flame retardants.

Replacement Considerations

Direct replacements within the same series include other DZ23Cxx-G3-18 variants with different Zener voltages. Cross-referencing electrical parameters such as dynamic resistance and leakage current is essential when substituting with devices from other manufacturers.
