BZX384B18-G3-08

Single Zener Diodes Overview

The BZX384B18-G3-08 is a single Zener diode manufactured by Vishay Semiconductors, designed for surface-mount applications. It features a nominal Zener voltage of 18 V with a tight tolerance of ±2%. The component operates within the BZX384-G series and utilizes an SOD-323-2 package. It supports a maximum power dissipation of 200 mW and maintains functionality across an extended temperature range from -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 50 Ohms.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% tolerance on the 18 V Zener voltage.
• Engineered for compact surface-mount designs using the standard SOD-323-2 footprint.
• Ensures reliable operation in demanding environments with a wide operating temperature range.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable low-voltage sources
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in portable electronic devices

Single Zener Diodes Procurement Notes

Verify the specific suffix G3-08 against official Vishay documentation to confirm lead-free compliance and reel packaging specifications. Ensure the ordering part number matches the exact voltage and tolerance requirements for your design. Cross-reference the manufacturer's latest datasheet to validate any potential obsolescence notices or parameter updates before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a high-precision 18 V reference is needed in a minimal surface-mount footprint. The ±2% tolerance makes it suitable for applications where tighter regulation than standard 5% parts is required. Consider the 200 mW power rating and thermal constraints of the SOD-323 package during PCB layout to ensure safe operation under continuous load conditions.

Single Zener Diodes Part Context

This device belongs to the BZX384-G series of small-signal Zener diodes. The series is characterized by its low-profile SOD-323 package, which facilitates automated assembly and space-efficient board layouts. Vishay produces this line to meet general-purpose industrial and consumer electronics demands for reliable voltage regulation components.

Single Zener Diodes Replacement Considerations

Check for direct substitutes within the BZX384 family with identical voltage and tolerance ratings. Verify pinout compatibility and thermal performance metrics against alternative manufacturers' SOD-323 Zener diodes before substitution.
