BZX84-A18,215

Single Zener Diodes Overview

The BZX84-A18,215 is a single Zener diode from the Nexperia BZX84 series, designed for low-power voltage regulation. It features a nominal Zener voltage of 18 V with a tight tolerance of ±1%. The device is housed in a compact SOT-23 (TO-236AB) surface-mount package, suitable for automated assembly. Key electrical parameters include a maximum power dissipation of 250 mW and a test current of 5 mA. It operates within a temperature range of -65 °C to +150 °C, ensuring reliability in demanding environments.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with ±1% tolerance for sensitive circuit applications
• Utilizes a small SOT-23 surface-mount package for efficient PCB space utilization
• Capable of operating at high junction temperatures up to 150 °C

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Over-voltage protection stages in consumer electronics
• Biasing networks in signal conditioning modules

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' confirms the ±1% tolerance requirement, as other variants like 'B' or 'C' offer wider tolerances. Ensure the ordering code includes ',215' to confirm reel packaging specifications. Cross-reference the manufacturer part number with official Nexperia documentation to validate authenticity and avoid counterfeit components during sourcing.

Single Zener Diodes Selection Notes

Select this component when tight voltage accuracy is critical, as the 'A' grade offers superior tolerance compared to standard grades. Consider the SOT-23 footprint compatibility with existing board layouts. Evaluate the 250 mW power rating against expected thermal conditions to ensure safe operation without derating issues in confined spaces.

Single Zener Diodes Part Context

This component belongs to the BZX84 family of low-power Zener diodes manufactured by Nexperia. The series is characterized by its use in general-purpose voltage regulation tasks across automotive, industrial, and consumer sectors. The BZX84-A variant specifically targets applications needing higher precision than the standard B or C tolerance grades provide.

Single Zener Diodes Replacement Considerations

Compatible substitutes include BZX84-B18,215 and BZX84-C18,215, though these offer ±2% and ±5% tolerances respectively. Direct replacements must maintain the SOT-23 package and 18 V nominal voltage. Verify that alternative sources meet the same AEC-Q101 qualification standards if used in automotive contexts.
