DZ23C16-G3-18

Overview

The DZ23C16-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 16 V with a ±5% tolerance and operates at a test current of 5 mA. The device has a maximum dynamic resistance of 40 Ω and a reverse leakage current of 0.05 μA at 12 V. Rated for power dissipation up to 300 mW on an FR-4 board, it supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common cathode configuration within a compact SOT-23 footprint
• Graded Zener voltages aligned with international E24 standards
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable DC levels
• 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 minimum order quantities. Ensure that the component meets RoHS compliance requirements and material categorization standards relevant to the target manufacturing region before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array is required in a small outline transistor package. Confirm that the 16 V breakdown voltage aligns with the circuit design constraints and that the 300 mW thermal rating is sufficient for the expected ambient operating conditions without excessive derating.

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 standard voltage values in the SOT-23 package, providing a space-efficient solution for general-purpose voltage regulation and protection tasks in consumer and industrial electronics.

Replacement Considerations

Direct replacements must match the 16 V nominal voltage, SOT-23-3 package, and dual common cathode configuration. Verify equivalent electrical parameters such as dynamic resistance and power dissipation capabilities to ensure functional compatibility in the existing circuit layout.
